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 the need for signature database updates.

Free Cloud Antivirus for Windows 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 which could arise in a user’s mind is that, would 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 10:

Panda Free Cloud Antivirus
Kaspersky Security Cloud Free
Comodo Cloud Antivirus.

2] Kaspersky Security Cloud Free

Kaspersky Security Cloud (basic version) is a free Antivirus solution for Windows computers which also offers secure connection(VPN) when browsing the internet and comes with adaptive security features. While it comes with two paid offerings, in this review we are talking about the free version which is worth for what it has to offer.

Kaspersky Security Cloud Free gives you remote control and management options that Kaspersky Free Antivirus does not support. That is the main difference between the two.
