Limitations & Advantages of Machine Learning & AI in Antivirus Software

 Limitations & Advantages of Machine Learning & AI in Antivirus Software

With regards to antivirus software, a few merchants are hailing machine learning as the silver projectile to malware — yet what amount of truth is there to these cases?

In today's post, we're going to investigate how machine learning is utilized in antivirus software and whether it truly is the ideal security arrangement.

How Accomplishes Machine Learning Work? 

In the antivirus industry, machine learning is commonly used to improve an item's detection abilities. Though ordinary detection innovation depends on coding rules for detecting malicious examples, machine learning algorithms construct a mathematical model based on test data to foresee whether a file is "acceptable" or "bad".

In basic terms, this involves using an algorithm to investigate the recognizable data points of two, manually made data sets: one that includes just malicious files, and one that includes just non-malicious files.

The algorithm then creates decides that permit it to distinguish the great files from the bad, without being provided with any guidance about what kinds of examples or data points to search for. A data point is any unit of information identified with a file, including the internal structure of a file, the compiler that was utilized, text assets gathered into the file and substantially more. The algorithm continues to ascertain and streamline its model until it winds up with an exact detection system that (in a perfect world) doesn't order any great programs as bad and any bad programs as great. It builds up its model by changing the weight or importance of every data point. With every cycle, the model shows signs of improvement at precisely detecting malicious and non-malicious files.

Machine Learning Can Help Distinguish New Malware

Machine learning helps antivirus software distinguish new threats without relying on signatures. Previously, antivirus software depended to a great extent on fingerprinting, which works by cross-referencing files against an enormous database of known malware.

The significant flaw here is that signature checkers can just identify malware that has been seen before. That is a rather enormous blind spot, given that a huge number of new malware variations are made each and every day. Machine learning, then again, can be trained to perceive the indications of good and bad files, enabling it to distinguish malicious examples and recognize malware – whether or not it's been seen before or not.

 

The Limitations of Machine Learning 

While machine learning can be an exceptionally powerful tool, innovation has its limitations.

1) Potential for Misuse

One of the key shortcomings of machine learning is that it doesn't understand the implications of the model it makes – it simply does it. It essentially utilizes the most effective, mathematically-demonstrated technique to process data and decides. As noted before, the algorithm is taken care of with a huge number of data points however without anybody explicitly telling it which data points are indicators for malware. That is up for the machine learning model to discover all alone.

The upshot of this is no human can ever truly know which data points may – according to the machine learning model – indicate a danger. It could be a single data point or a particular combination of 20 data points. A spurred attacker might discover how the model uses these boundaries to distinguish a danger and use it to their advantage. Changing one explicit, seemingly non-important data point in a malicious file could be sufficient to fool the model into classifying malware as sheltered and undermine the entire model. To correct the issue, the seller would need to add the manipulated file to the data set and recalculate the whole model, which could take days or weeks. Unfortunately, this despite everything wouldn't fix the underlying issue – considerably after the model was remade, it would simply involve time until the attacker found another data point or combination of data points that could be utilized to trick the machine learning system.

2) Requires an Enormous, Well-labelled Dataset

Machine learning systems are just tantamount to the data they are supplied with. Training a successful model requires a tremendous number of data inputs, every one of which should be effectively labelled. These names help the model understand certain attributes about the data (for example whether a file is spotless, malicious or potentially unwanted).

Be that as it may, the model's capacity to adapt successfully relies upon the dataset being totally labelled, which can be troublesome and asset-intensive to accomplish. A single mislabelled input among a large number of completely labelled data points may not seem like a serious deal, yet in the event that the model uses the mislabelled input to form a choice, it can bring about blunders that are then utilized as the reason for future learning. This makes a snowball impact that can have critical repercussions further down the line.

Conclusion

Machine learning is a ground-breaking innovation that may play an increasingly important job in the cybersecurity world in the years ahead. Be that as it may, as referenced above, it is imperfect and limitations. Relying on the Antivirus Software that is controlled solely by AI or machine learning may leave you defenceless against malware and other threats.

 

New Antivirus Software in PC Will Demolish Existing Viruses

 New Antivirus Software in PC Will Demolish Existing Viruses

Antivirus software is the most useful asset against infection, yet what happens on the off chance that you get a virus when you aren't protected? Fortunately, security organizations have thought about this issue, and their security suites give the ideal arrangement.

All antivirus programs permit you to perform a top to bottom scans of your PC. Any malware in your system, regardless of to what extent it's been there, can be effortlessly recognized and eradicated. Premium antivirus choices can spot over 95% of known viruses and new infections, so it's anything but difficult to determine issues rapidly.

In any case, solving a malware issue necessitates that you notice the infection and make a move.

Indications of Infection 

Without antivirus installed, it might be hard to recognize an infection. Many viruses work in the foundation without you realizing it. On the off chance that you may have contracted malware, search for the following signs.

1) Diminished Function 

Speed and functionality issues are often the consequence of an infection. In the event that you notice an unexplained slowdown or your device crashes more than expected, it might be a warning.

2) Pop-up Ads 

Pop-up ads used to be a typical event, yet not any longer. This intrusive advertising style must be installed by means of malware, so on the off chance that anything pops up, then it's the motivation for concern.

3) Suspicious Activity 

Close by unexplained pop-ups, suspicious activity is an indication of an issue. Run of the mill models includes programs opening and closing, downloads launching, and increased CPU use. 

4) Spam Messages 

Often, the main indication of an infection is another person telling you they've gotten a strange message from you. Malware can commandeer our mail accounts, sending spam to your contacts in an endeavour to spread the virus further.

5) Browser Homepage and Toolbars Change 

Malware has an annoying propensity for changing your browser homepage and adding toolbars. On the off chance that you out of nowhere observe another default search engine or an unexplained re-direct when you open the internet, it's an ideal opportunity to search for an answer. Fortunately, regardless of whether you speculate you have an infection, the procedure to affirm and expel it is moderately straightforward.

How Antivirus Works 

Antivirus software can accurately recognize and quarantine likely infections. The programs run from a rundown of signature-based or behavioral-based threats. When the antivirus flags any suspicious codes or actions, it looks at them to the database to build up the danger level. These reserves of information are often community-oriented and normally updated, so many antivirus suppliers share knowledge.

Fortunately, this system implies that any security suite can recognize any existing virus. Regardless of whether the infection has been in your PC for months – or years! – running an inside and out system scan will banner and resolve the issue.

Nonetheless, not all antivirus titles are made equivalent. A few suppliers can't ensure total protection, which could result in malware falling through the breaks. Investing in Total Security Software with a close to 100% detection rate will give you the most obvious opportunity with regards to progress.

Instructions to Expel a Virus 

On the off chance that you speculate you have a virus, follow this procedure to evacuate the issue rapidly.

1) Pick a Best Antivirus Software 

Do your research before you picked your antivirus. Check out our reviews of the best items to determine which is the Best Antivirus Software for your requirement. You don't need to focus on the most costly; a few major security organizations offer a free elective that despite everything ensures protection.

2) Make an Account and Download the Software 

Most antivirus suppliers expect you to make an account. While now is the right time consuming, you'll get information about updates and changes.

3) Adhere to the On-Screen Instructions for Installation 

Your antivirus software will begin an automatic installation process. You'll have to have administrator rights on the PC, and it will require accepting terms and conditions. All antiviruses likewise require plate space, so ensure your hard drive isn't full.

4) Decide to Run a "Full Scan" of Your Whole System 

Antivirus as a rule accompanies three scan types. The "Speedy Scan" will do a fundamental check of your system, while a 'Full Scan' goes a lot further. The third sort is automatic scans, which can be set to run intermittently.

5) Erase the Virus Permanently 

Once the antivirus has detected the danger, it will then place it in quarantine. This implies it can't function yet at the same time exists in your system. You'll need to determine that you need to erase it. This function exists with the goal that the security suite doesn't evacuate your basic files accidentally.

6) Set-up Automatic Scans 

When the virus is erased, it's additionally worth setting up the automatic scan feature to avoid recurrent infection.

 

Stay Watchful for Forged Antivirus Software!

 Stay Watchful for Forged 

Antivirus Software!

A great many purchasers and businesses use antivirus software to protect their networks and devices from cyber threats. In spite of the fact that there are many kinds of antivirus software, they are completely intended to distinguish and expel — or quarantine when removal is beyond the realm of imagination — viruses just as other forms of malware. Unfortunately, however, hackers have profited by the increasingly quick adoption pace of antivirus software by using it to convey malware.

What is a Fake Antivirus Software? 

Otherwise called rogue security software, fake antivirus software is malware disguised as legitimate antivirus software. It uses the properties of social engineering to fool victims into downloading it. The fake antivirus software doesn't uncover its actual self. Rather, it would appear that legitimate antivirus software that is ready to protect your PC or network from cyber threats.

Fake antivirus software is utilized for money-related purposes by hackers. In other words, hackers send fake antivirus software on PCs and networks to fool the victim into making a payment. Most kinds of fake antivirus software request that the victim pays an expense to expel the recognized danger or threats.

How Fake Antivirus Software Spreads 

Hackers utilize an assortment of strategies to send fake antivirus software, one of which is social media. In the event that a hacker gains access to a client's social media profile, the individual may message the victim's friends or associations with links to download the fake antivirus software. Every friend who then clicks the link and continues to download the fake antivirus software will then be infected also.

Email is another regular vector used to convey and spread fake antivirus software. Regardless of whether an email appears to be from somebody you know, the "from" address may have been spoofed by a hacker. Hackers use email to convey a wide range of malware, one of which is fake antivirus software.

Indications of Fake Antivirus Software 

How would you know whether your PC or network is suffering from fake antivirus software? The obvious symptom of a fake antivirus software infection is visit pop-ups saying that your PC is infected with a virus. And when you endeavour to evacuate the virus, it will request that you buy the full form of the software.

You may experience performance issues with the PC or devices infected with fake antivirus software. Like other software, fake antivirus software expects assets to run. As it devours your PC's or device's assets, you'll likely experience slower speeds.

 

Know More About Avoiding Fraud or Scams on Internet by Antivirus Software

 Know More About Avoiding Fraud or Scams on Internet by Antivirus Software

In recent times we are witnessing an undeniable boom on the Internet, as a platform from which very different procedures can be carried out: from paying for a movie ticket to getting a plane ticket or booking a hotel room, to carrying out operations with Our bank. Although the use of the Internet in these procedures has the advantage of speed, convenience, versatility, economy, etc., this circumstance can be used by so-called "cybercriminals" to commit scams and fraud that we can avoid or, at least minimize, following a series of tips when operating online.

An example of a widespread scam on the Internet is the so-called “phishing” or identity theft. It is a very widespread fraudulent technique through which fraudulent emails are sent that, apparently, come from trusted sources (banks, organizations, public bodies). In this email, they usually appear Webs equal to the real ones; logos, symbols, and corporate image identical to the official ones and links that lead to the fraudulent website.

The modus operandi used is that unsolicited emails are sent to email addresses in which we are asked to check the bank account, click on a link or link provided and where data such as username, password or password are requested, DNI, Social Security number, ...

Likewise, we may receive unsolicited emails in which users are alerted that their account is being used fraudulently and that if it is not answered, providing the access data to it, it will be immediately cancelled.

How Can We, at the Least Minimize the Effects of Phishing?

- Delete any mail that may seem suspicious or whose origin is not known, without opening it. Delete any spam or junk mail ( do not open its attachments, or access its links ).

- Avoid chain letters, as these are a source of junk mail (spam), and a way of collecting email addresses potential sources of phishing. To do this, it is best to send emails with hidden recipients.

- Have an updated ANTIVIRUS installed on the computer, in addition to having the latest versions of the software for the computer programs. This is extendable to smartphones and tablets. If an antivirus product is installed, it is updated periodically. This antivirus can contain different operations such as anti-phishing functions that analyse the access pages to verify that they are safe and that identity is not stolen. In addition to antivirus, you must protect yourself with anti-spyware, malware, and adware programs.

- If an antivirus product is installed, it is updated periodically. This antivirus can contain different operations such as anti-phishing functions that analyse the access pages to verify that they are safe and identity is not stolen. In addition to antivirus, you must protect yourself with anti-spyware, malware, and adware programs.

- Do not click on the links that come in supposedly fraudulent or dubious emails, since this can lead to the hypothetical fraudulent pages (it is always safer to type the address directly in the address bar of the computer ).

- Remember that a bank will never request user information, passwords, and personal data through an email.

- Before entering personal data on a certain web page, make sure that it is a secure server (the page address begins with https, presence of a padlock in the address bar).

- If you have received any of these emails or if you are the victim of deception of this type, do not hesitate to notify the entity whose identity has been impersonated and report it to the Police or the Civil Guard.

Shopping online is safe if you follow a series of tips or a few minimum security rules.

- Perform an examination of the online store or e-commerce before making a purchase, and compare prices.

- It is necessary to inform as much as possible of the data of the selling party (address, telephone, ...). The well-known Internet search engines can be a good option for the collation of data.

- Make purchases in electronic stores or auction pages that offer confidence (because they have been used before or because they have favourable opinions from other people). 

check the information that exists about the company responsible for the website. It can be verified, in the "Who we are" section, electronic security seals such as VeriSign, Trust-e, or Confianza Online certificates should be included, which allow confirming the authenticity of the page. It is recommended, although it may be tedious, to carefully read the contact information and also the "Legal Area" section or the "Terms and Conditions". It can also be useful to read the frequently asked questions and verify that they have a customer service in case you have to claim. Web pages that do not offer any identifying information that allows their location should be avoided at all costs.

- Be suspicious of ads with excessively low prices (they may hide fraud or a manifest lack of quality).

- At equal prices, always buy on Spanish or European Union websites, since Spanish and European regulations are a guarantee for the resolution of possible claims. Be wary of bargain ads when the ad is in incorrect or poorly written language.

- Do not buy when an advertisement or offer comes from an unknown or unsolicited site (they can be a source of spam or phishing).

- Check that the prices offered include taxes and do not present hidden additional costs, such as management costs or fees.

- Be wary of business proposals that sound too good to be true (immediate solution of financial problems, excellent job opportunities, investments without any risk, offering gifts, ...).

- If a transaction is made with a mobile terminal or tablet, it is recommended that said transaction be made through a mobile application, if it exists, instead of the Internet page itself. Many companies have applications for mobiles and tablets that allow the purchase process to be carried out safely. Therefore, it is recommended to download and install it on the mobile device to proceed from the application itself and not from the mobile browser.

- It is necessary to try to avoid connection networks that are public or not protected with an access password, as well as to carry out these operations in phone booths and the like. In these conditions, cybercriminals can access more easily since there are fewer security measures.

- Be suspicious of advertisements in which they request to use a premium rate telephone.

- Use in Internet transactions trade always safe page starts with https, a padlock in the address bar.

- Always try to pay cash on delivery, discarding money remittances to a certain address, and without providing bank account details. Go to secure payment methods. If you don't have a credit card, Pay Pal offers a fast and secure way to make purchases or transfer money. If a card is used, check that it has the correct CVV on the back. Many banks offer the option of sending messages when a certain operation is made with the card. It is advisable to use bank transfers as a form of payment as it allows you to track the money. Runaway from money transfer companies like Western Union, Money Gram, ..., as they are frequently used by criminals by leaving no trace. If you are asked for advance payments on an online page, don't do it. Likewise,

- It is vitally important, especially with regard to possible claims, to download and store in a safe place all the invoices and receipts that the company sends. These documents serve as a guarantee in case of problems, as well as to have precise control of the expenses that are being made.

 

What Are the Benefits of Cloud Antivirus Software

 What Are the Benefits of Cloud Antivirus Software

Occasionally we browse a website that offers a link to remove possible viruses and malware that are installed on the PC. Can you trust them? After all, we do not have that security of having a program on the computer whose task is specifically this, whether it be a paid or free solution, apart from the fact that there are so many deceptive links on the internet that we are left with the flea behind the ear that that click may represent some plague.

At first, antivirus in the cloud are simple and good quality solutions, but with reservations. They are only useful tools when they work side by side with the programs on the computer because they look for specific malicious files, but in a superficial way, and they were not developed to replace the classic antivirus, but to complement its functionality. Either way, it is important to be careful about the website offering the link. A good example is the Adobe Flash Player download site, which is above suspicion:

As it is an official website, we have a huge guarantee that the link is not malware. The operation is quite simple: with the download of a very small file (less than 1 MB), a quick scan will be made on the hard disk for malicious files and the system will automatically take action if it finds any problem, either deleting it or placing it under quarantine, providing additional protection to the machine's antivirus.

Another solution that is becoming increasingly popular is the full-featured Cloud Antivirus. They are different classic programs that do not work in the background but come into operation every time we open a file, a method known as on-access protection. This approach is the subject of much discussion, as some claim that background protection is essential while others say it is not so important.

The idea of ​​a program running in the background can provide good security, but currently, it is really not so relevant for a simple reason: once the virus is installed, it is hardly detected in antivirus scans. This makes on-access protection more and more important, but also if it does not detect malware at the time it will be installed anyway.

So which is the best? If any antivirus was 100% effective, it would sell like water, so it depends on which approach you choose since the two together would penalize the machine's processing and memory usage.

Cloud Antivirus Software Are Noticeably Lighter Than Traditional Ones.

At the end of the day, what ends up counting is how to use the computer, what websites are accessed, and what downloads the user usually makes. Illegal download sites, pornography, and the like usually have tons of viruses and malware, so, regardless of the solution chosen, common sense in navigation ends up being the most important factor.

 10 Cyber Threats in the Spotlight

Attacks on computer equipment have increased in recent months. Open networks, public Wi-Fi, remote connections, Internet of things (IoT), proximity payments, cloud computing ... The list and types of computer threats that put security at risk are long. Cybercrime is a real problem.

Knowing the dangers to the integrity of sensitive business data is the first step to ensuring its protection.

Types of Computer Threats You Need to Know

16.7 million consumers experienced identity theft in 2017 ( JavelinStrategy ), but there is much room for improvement as, according to a 2018 study by Juniper Research, cybercriminals will hijack about 33 billion records in 2023.

The Ponemon Institute for IBM study of the cost of a data breach in 2018 reveals that the average cost of a data breach to companies worldwide is $ 3.86 million and the average time it takes to identify a breach data breach is 196 days.

The first step to avoid the consequences of these attacks is to know the types of computer threats that exist. They are as follows:

• Spam. Spam is one of the most popular security threats. Many people are affected each year by spam that misrepresents their information by tricking the user into following some of the links it contains.
• Farming. It aims to convince the user to visit a malicious and illegitimate website by redirecting the legitimate URL. Once inside, the goal of cybercriminals is to get the user to give them their personal information.
• Phishing. Unfortunately, it is one of the easiest types of computer threats to execute. It consists of sending fake emails or messages that look like emails sent by legitimate companies. Thus, the user is made to think that it is a legitimate company and the chances that personal and financial information will be shared increase.
• Ransomware. "Wannacry" and "Petya" are examples of the dangerous potential of this threat. Hackers sneak into their victims' computers and restrict access to their system and files. They then request payment in exchange for retrieving control of their data.
• Computer Worm. This is a very common security threat. A worm works alone lives in the computer and spreads by sending itself to others.
• Spyware / Trojan Horse. A Trojan horse is a malicious program that looks like legitimate software. While it is installed on the user's computer, it runs automatically and spies on their system or deletes their files.
• Distributed Denial of Service Attack. (DDoS)The attacking approach is to contact a particular website or server over and over again. Increase the volume of traffic and crash the website/server. The malicious user generally uses a zombie computer network.
• Zombie Team Network. This is a way of performing various security threats. The malicious user takes the administration of multiple computers and controls them remotely.
• Malware. This is the common name given to various security threats that infiltrate and damage a computer.
• Virus. A virus is always hidden in a legitimate software or website and infects the affected computer and can spread all those that are in your contact list.

The types of computer threats increase every day putting security in check. Fortunately, there are ways to protect yourself against most of them, such as Total Security Software. Caution is the best strategy.

 

Fear of Cyber Threats That Every Small Enterprises Must Know

 Fear of Cyber Threats That Every Small Enterprises Must Know

If you run a business, you need a website. Today's technology makes getting started very easy. A website is a very valuable asset for your brand, unlike a Facebook page, which could be closed at any time and for any reason. A web page is a place where your clients can find the answers to all their questions, they can even discover how to get to your physical location. And if your website is totally focused on your business, it is important that you know what computer threats you may encounter and what type of maintenance you should carry out.

According to Kaspersky Lab, 60% of SMEs disappear quickly more than six months after receiving a cyber-attack. It's easy to see why: Exposing sensitive information can damage trust with users.

The best of all? You don't need a large budget to adequately protect your website against computer threats. But you do need a proactive approach to check the security of your website and implement measures to prevent them.

7 Types of Common Computer Threats

Web security covers a wide repertoire of attacks and solutions, but here are the seven most common computer threats:

1. Malware.
2. SQL injection.
3. Cross-Site Scripting (XSS).
4. Interception
5. Password attacks.
6. DDoS attack.
7. Incorrect security settings.

While there are other computer threats that can affect the security of your website, protecting your page against these seven types of cybersecurity vulnerabilities will help you stay on the right track.

1. Malware

Malware is malicious software designed to infect and damage a system. Since it is a broad term, malware encompasses vulnerabilities ranging from computer viruses to adware that can infect both computers and web pages. A website attacked by malware exposes sensitive data, including your customers' information.

Malware attacks can be very damaging for businesses, especially those that are unable to recognize them.

2. SQL Injection

Vulnerabilities often occur when a page contains a security flaw in the code that allows those with malicious intent to attack or gain control. This is commonly caused by problems in outdated WordPress plugins or other tools used on your website.

SQL Injection is a type of cyber-attack that involves malicious SQL statements or application code being injected into user input fields. This process allows attackers to gain access to the web backend or corrupted content in the database.

3. Cross-site Scripting (XSS)

This type of vulnerability, also called XSS, is another of the common types of computer threats that your website can suffer. Unlike SQL Injection, XSS occurs when lines of malicious JavaScript code are injected into a page to target users of that website, manipulating client-side scripts.

These scripts hijack user sessions via a web page's search bar or comments (via the backend). This can disrupt the web and redirect users to other malicious pages that may appear as seemingly normal-looking pages, but may actually steal your information.

4. Interception

An Interception attack occurs when a hacker captures data that users send to a website, and then uses it for their own benefit. It can be contact information or sensitive data like a credit card. Cybercriminals then sell this data or make their own purchases.

It is important to install an SSL certificate on your website to protect confidential data. SSL encrypts the connections between the visitor's browser and the web server, to establish a secure session. This protects buyers from cyberattacks, such as by Interception.

So, does your website need an SSL certificate even if you don't sell online? The answer is yes.

5. Password Attacks

Some hackers guess passwords or use dictionary tools and programs to try different combinations until they find them.

In some cases, the keylogger is also used to gain access to user accounts. The keylogger recognizes every keystroke made by a user. The results are communicated back to the hackers who initially installed these programs.

Many websites lack strong passwords, making login attempts incredibly easy. Here are some ways to protect your website:

• Request a strong and unique combination of passwords.
• Ask users to change their passwords regularly.
• Requires two-step authentication to confirm user access.

6. DDoS Attack

A distributed denial of service (DDoS) attack occurs when a web server receives a lot of traffic or requests that the system is overloaded or flooded.

This is fake traffic from computers controlled by attackers, often called botnets. A botnet is a number of devices connected to the Internet that run one or more bots.

When the webserver is overloaded with traffic or requests, the web loads poorly or fails to load. With enough force behind these attacks, the web server can crash, completely disabling the page.

7. Incorrect Security Settings

This attack occurs when the security configurations of a website have security holes that can lead to various vulnerabilities. This often occurs due to a lack of proper maintenance of your page or improper configuration of the web application.

Incorrect security settings allow hackers to access private data or web functions that can completely compromise the system. In these situations, the data can also be stolen or modified.

Final Thoughts on Cyber Threats

Spending time learning about the most common vulnerabilities in web security is an important first step in defending your company's website. The second step is to take action, make changes, and install TOTAL SECURITY SOFTWARE to protect your data and that of your customers.

 

Why to Have The Best Antivirus Software?

 Why to Have The Best Antivirus Software?

Today we are connected to the internet throughout the day and we totally depend on it for our communications. Messages, chats, searches, email inquiries, in some cases even phone calls ... If just a few years ago we only had access from our homes, today it has spread to our smartphones or even to many public places (shopping centres, restaurants, outdoor areas ...)

But, although the advantages offered by having internet access are infinite, we must also be aware that it can generate some problems, the main one being viruses, Trojans or spyware, among others. To prevent them from "sneaking" into our devices and causing us significant damage, today we are going to talk about why it is important to have an antivirus, not only on our computer but on any device with which we surf the internet.

Why Install an Antivirus?

A virus can get inside our device without our realizing it, since not only by avoiding “malicious” pages we are safe from them. They can be installed by opening a pop-up window from a site we thought was safe, downloading a file we thought was harmless, etc. To avoid this virtual insecurity, it is necessary to have an antivirus that previously analyzes each movement we make of this type and gives us the go-ahead before continuing. These are the main reasons why we must have an antivirus as a virtual security method.

Malicious Web Pages.

Although common sense makes us determine which pages are safe and which ones may have malicious content, sometimes we find websites that make us download some type of code that is installed on our device without us noticing. An antivirus will warn us in case something is opened, downloaded, or is going to install something outside of the "normal" one, thus making us safe at all times.

Infected Emails.

Infected files are also easy to run via email. Not only through unknown emails or spam, but sometimes some of our contacts can send viruses without being aware of themselves; that's why it's easy for us to trust ourselves and download a file that is really malicious.

Documents.

Every document that is opened, even office files such as Word or Excel, an antivirus detects whether the source is reliable or not. Through USB it is also easy to pass malicious documents and an antivirus allows us to analyze it and eliminate any suspicion.

Data Espionage.

An antivirus also protects us from data espionage. For this, you need an antivirus that detects spyware and increases the security of our browsing when we have to enter personal information on certain pages.

Is an Antivirus Necessary on the Mobile?

If a few years ago we only used the mobile phone to call or send SMS, today we all use it to chat, check email, use countless APPs, even make voice calls ... How we use the Internet through our device Mobile makes us constantly at risk if we do not give it the proper use. We must be careful with unreliable applications that we install on our phone, since, although most are safe, there is a percentage that can put our mobile at risk.

Avoid Viruses on Your Phone

Avoid Automatic Downloads.

In addition to always downloading from safe sites, we can also protect ourselves in mobile settings. In many devices there is the option to disable the download from sites that are "unknown sources", so by checking it you will be avoiding automatic downloads when you browse pages with pop-up windows or that by mistake you end up in unreliable sites.

Responsible Navigation.

Although most web pages are already responsive, browsing from a mobile phone is not the same as from a computer. Although in most cases from the smartphone it is easier and more intuitive to operate within a site, on pages where there is a lot of advertising or pop-ups it is really exhausting. Therefore, it is necessary to navigate responsibly and try to avoid all those pages that put our online security at risk.

Antivirus on Mobile.

But even if you are careful, as we have seen sometimes it is easy for a virus to install itself without us being aware. That is why there is the possibility of having an antivirus on our mobile. The main drawback is that it will occupy space on the phone and in many cases, it will slow down its performance since it will analyze each page, download, new file ... Although there are many people for or against, if from the mobile you are going to browse that it is not always going to be security, without a doubt you should install an antivirus on your smartphone.
