Sometimes we need a portable antivirus to scan some files on to go, and free online antivirus tools are one such security tool that comes in handy such times in order to scan files to detect and remove infected files.
One of the usual security tips is one that recommends not downloading files from unreliable sources. Either from an unknown email or from a website that you access for the first time, we must be cautious with those suspicious files. At some point, you have seen how your computer has been attacked by some type of virus or malware by downloading files from some websites.
Although the normal thing is that most of us have a security tool like antivirus installed on the computer to detect different types of infected files. But when using someone else’s computer without an antivirus to download files may open doors to different malware and spyware.
In that case, online antivirus tools come to the rescue. They are portable antivirus engines that we can use from the browser.
Here we will list some of the best online antiviruses that we can use for free to detect and eliminate viruses on your computer.
As far as free online antivirus is concerned, 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 analysis of the system to detect and eliminate infected files and those that are more focused on analyzing files individually.
Advantages Of Online Antivirus Tools:
An online antivirus 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.
- Availability: Regardless of the computer we are using, we can have access to any of them since they do not require installations. All you have to do is go to the website of the particular antivirus to carry out any analysis. All we need is a web browser.
- Various results: Many of the online antiviruses carry out inspection of files with different security tools. This makes the result very reliable since we can check what each antivirus says about the file analysis.
- Free: we can find a lot of free antiviruses online, like the ones we have mentioned below.
Disadvantages Of Online Antivirus Tools:
- Less effective: They are not as complete as the antivirus that is installed on the computer.
- No permanent protection: They do not offer permanent protection. They allow analysis or protection until 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.
