Why it is important to have an these days

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

But, although the advantages offered by having internet access are endless, 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 us noticing, because not only by avoiding the “malicious” pages you are safe from them. They can be installed by opening a pop-up window of a site that we thought safe, by downloading a file that 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 approval before continuing. These are the main reasons why we should have the best antivirus as a virtual security method.

  • Malicious web pages. Although common sense makes us determine which pages are safe and which may have malicious content, sometimes we find websites that make us download some type of code that is installed on our device without our noticing. An antivirus will notify us in the event that it is opened, downloaded or installed something outside the “normal”, therefore making us safe at all times.
  • Infected emails. Through email, it is also easy for infected files to run. Not only through unknown emails or spam, but sometimes some of our contacts can send viruses without being aware of them; That is why it is easy for us to trust and download a file that is really malicious.
  • Documents. Each document that is opened, even from office files such as Word or Excel, an antivirus detects whether the source is reliable or not. It is also easy to pass malicious documents through USB and an antivirus allows us to analyze it and eliminate any suspicion.
  • Data spying. An antivirus also protects us from data espionage. For this, we need an antivirus that detects spyware and increases the security of our browsing when in certain pages we have to enter personal information.
