Types of viruses

It is of utmost importance to note that there are different viruses that can compromise the security of your electronic devices and all the files they contain. Each different virus has a different way of operating.

  • Trojans: This virus was specifically designed to spy on users. It is usually found in attachments, programs or applications and is virtually undetectable to the naked eye. Very difficult to remove without a specific program to do so.
  • Scripting virus: Generally speaking, this type of virus is a script embedded in websites. Because it is written in a basic programming language, browsers do not consider them as viruses. The consequences of having this virus are spamming and file deletion.
  • Program viruses: these are very dangerous viruses that are attached to infested files or executable files, then, when these files are opened or programs are executed, they are activated.
  • Macro viruses: these are usually found in emails or downloaded files and are seen as macros in Word or Excel files.
  • Worms: the main characteristic of these viruses is their rapid propagation through emails, they damage files as they pass through and can infest many devices at once.

Advantages of online antivirus

Just like traditional antivirus, online antivirus has certain advantages. Below is a list of the advantages so that you can make a better decision when looking for an antivirus for your computer:


It is important to bear in mind that the versions found on the antivirus web portals are the most updated, that is, they are the latest versions offered by their creators. The advantage of this is that you do not need to constantly download updates to your devices since they are always available.


Because these antiviruses do not require tedious installations, compatibility with your computer is eliminated. This means that regardless of the computer you have, you can make use of the antivirus you choose online. In addition to this, because nothing needs to be downloaded, you can scan any computer you wish.


Different antivirus programs use different tools for file analysis. Thanks to the fact that it is not necessary to download them to the computer, you can use different online antivirus as you want, to compare the results of the analysis and thus, to have a more accurate judgment at the time of trusting only one result.

Disadvantages of online antivirus

We have already seen all the advantages of using this type of application to scan and clean the files on our computers. However, not everything is good, here are a couple of disadvantages of this type of antivirus:


Obviously, being a fast alternative that is available online, this type of antivirus sacrifices a bit of efficiency in favor of availability. Also, they are not as complete as the downloadable versions and only work to scan specific files, therefore, not all the files on your computer will be scanned for viruses. On the other hand, they do not protect sensitive areas of computers nor do they have advanced functions to do a thorough job.

Short duration of protection

 The scanning and protection provided by this type of antivirus depend solely and exclusively on the time the Internet browser is running. This means that when the browser is closed, the computer is vulnerable to any malware or virus attack.


Because they are not as complete as the downloadable antivirus, they tend not to eliminate all types of viruses found. On the other hand, sometimes these antivirus can point out that some files are infected when they are not.

What is the best free virus scanner on the Internet?

This position is disputed by many antiviruses that are found on the network and it is risky to say which is the best of them since they all use different scanning tools and can help us at different levels. However, many experts point out that one of the best free antivirus that we can get online is:
