15 Free Online virus scanners to Secure Your Computer and Mobiles

free online virus scanners

Most of the Antivirus providers are providing free online scanning tools. Few are working well by using their cloud-based server remotely without installing the required software.

But online virus checking does not replace real antivirus software. If I find any suspicious activity on my computer or servers, here is my favorite list of free online virus scanners, which I use in my regular work.

What is an Online Virus Scanner?

The online virus scanners are specially designed web services and they check on your device from a remote server. If they find any suspicious files on your computer, it detects and provides a quick and easy solution without downloading and installing big security software.

All virus scanners are not similar in their functions. Every tool is having different options with its accuracy, customization features and more.

How to scan my computer with free online virus scanners?

For a few years, online antivirus was reduced to a trickle. For a few years, it worked mostly with the Internet Explorer browser and we could scan our computers. Since then, the few online antivirus programs that remain require you to install a “module” to scan your PC for online viruses and remove them.

Therefore, rather than making an online PC analysis to use another antivirus, you prefer to use virus removal software available to you by the great names of antivirus vendors. They detect and remove viruses, Trojans, and other malware on your computer.
