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 centers, 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 can 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 the event that something is opened, downloaded or is going to
install something outside 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 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 means that we are 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 the
phone
- Avoid
automatic downloads. In
addition to always downloading from safe sites, we can also protect
ourselves in the 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-up windows 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.
