Best free Cloud Antivirus for Windows computers

A cloud-based antivirus software does not store the virus definitions on your Windows computer. Rather than using your computer’s processing power, this cloud-based antivirus sends data about potentially malicious files to the company’s servers for analysis. This approach is intended to take advantage of the latest signatures without needing signature database updates.

Free Cloud Antivirus for Windows 11/10

A Cloud Antivirus is an antivirus software that stores its definitions on the cloud – i.e., on the company’s own servers. As a result of this, they do not occupy much disk space. They are also fast and do not consume many resources.

One question that could arise in a user’s mind is that, he or she be still protected when not connected to the Internet.

“Yes, you do not need to be connected to the Internet all the time in order to be protected. Cloud Antivirus stores a “local cache copy” of Collective Intelligence for offline operation. As soon as you disconnect, Cloud Antivirus still works in the background, checking every file against its local cache of detections. This local cache includes, amongst other things, detection for all malware files which are currently in circulation and affecting users.”

Here are some of the best free Cloud-based Antivirus available for Windows 11/10:

1. Panda Free Cloud Antivirus
2. Kaspersky Security Cloud Free
3. Comodo Cloud Antivirus
4. Crystal Security.
