Surely at some point you probably have seen your computer has been infected by some type of virus or malware. Although normally everyone should’ve a security tool on their computer, the truth is that in a pinch we can always use some free online antivirus that we can find on the Internet.

When it comes to free online antivirus, it is important to know that they are not designed to replace antivirus programs, since online tools do not offer real-time protection. In addition, it is necessary to differentiate between online tools that perform a complete system analysis to detect and eliminate infected files and those that are more focused on analyzing files individually. Of course, we must bear in mind that despite being online solutions, in some of them we will have to download an executable to be able to scan our computer for viruses.

Advantages And Disadvantages Of Online Antivirus Tools

An online antivirus tool is an online program or application that we can run directly from our browser to scan our computer or certain files to detect any virus or threat. This means that they offer certain advantages over traditional antivirus:

  • Constant Update: the versions available through its official website will always be the latest versions offered by its developer.
  • Availability: Regardless of the computer we are using we can have access to any of them since they do not require installations. It would be enough to go to the website of the antivirus tool to carry out any analysis, all we need is a web browser.
  • Multiple Results: Many of the online antivirus perform scans with different security tools, this makes the result very reliable since we can check what each antivirus says about the analysis of the file.
  • Free: we can find a lot of free antivirus online, like the ones shown below.

But not all that glitters is gold and the use of this type of tool also has certain drawbacks:

  • Less Effective: They are not as complete as the antivirus that are installed on the computer.
  • No Permanent Protection: They do not offer permanent protection. They allow an analysis or protection to be carried out but this ends when we close the browser.
  • They Only Serve To Scan: They scan our computer or certain files in search of viruses but they do not usually protect sensitive areas of the system, nor do they have advanced functions for the control of emails, etc.
