Best free Cloud Antivirus for Windows 10/8/7

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

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.”

Currently, Panda, Kaspersky and Comodo are some good free cloud antivirus software, currently available for Windows.

Cloud Antivirus from Panda is now called Panda Free Antivirus.  This Cloud Antivirus is compatible with other antivirus software and is available in two flavors: Free Edition and Pro.

2] Kaspersky Security Cloud Free

Kaspersky Security Cloud Free Review

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.

3] Comodo Cloud Antivirus

Comodo Free Cloud Antivirus

Comodo Cloud Antivirus offers real-time antivirus monitoring and uses a powerful combination of virus monitoring, auto-sandbox and behavior analysis technologies to immediately protect your computer from all known and unknown malware.

    Cloud Antivirus from Panda not compatible with other antivirus software ?

    Please read:, you will note ‘Ability to run alongside other AVs and Anti-Spyware: can now be run alongside other security tools and scanners’.

  2. Have been using Panda Cloud Antivirus [Free Ediion] since it first launched as a beta release back in 2009. It’s remarkably lightweight albeit powerful. It stops all kinds of threats without compromising the performance. Highly recommend it!

    I haven’t used Panda CA myself but have seen it working on my friend’s laptop. And, both of us found it great. It’s free yet powerful.

    I have looked at Panda Cloud AV a few times but am wary of it clashing with my other security software. Even though I am extremely interested in any form of 2nd line defense I will hold back for a wee bit longer until I have seen it working on someone else PC and read a few more reviews on it. I suppose I am old school when it comes to security programs, no two programs doing the same job at the same time due to clashes. So come on Panda prove this old time thinker wrong and get some links to INDEPENDENT reviews made available on your site

    I think you need to have a fast broadband connection for this.

  6. Al Huger

    The current version of Immunet Protect does not have the ASK toolbar installed. For more information please see:

  7. ^ Hi Al, The one I downloaded did have the Ask toolbar; but good to see that the latest version does not have it.

  8. Juan Figueroa

    I use AVAST free, should i ditch it and use one of these presented here, specially Immunet, the
    “Fast Antivirus” and “Light” sounds good to me since my laptop is not that good in terms of CPU.

  9. Danny

    Does a Windows 8.1 tablet need an antivirus software? my tab is an Acer Iconia W4-820

  10. Serpher

    I’ve been using Immunet since it came out. A decent av, but ClamAV works a bit clunky.
