Immunet is a free, cloud-based , community-driven antivirus application, using the ClamAV and its own engine. The software is complete with existing antivirus software . On January 5, 2011 it was announced that Immunet had been acquired by Sourcefire . [2] [3]

The application is free of charge, and claims to be fast and provide up-to-date protection against threats. [4] Virus signature files are stored in the cloud. Once a virus is detected and blocked for one user, all other Immunet users receive the same protection almost instantly. The software is noted for its ability to allow individual users to easily author their own signatures. [5]


Source, available in two editions, Free (for personal use), [6] [7] [8] and More (for commercial use). As of June 10, 2014, the commercial version was discontinued, though Cisco (having acquired SourceFire) continued to support the free version. [9]

At version 3.0 as of 2014 , the Immunet Free offers protection based on the virus definitions in the cloud, and an option to include the ClamAV off-line virus definitions for use when not connected to the Internet. Immunet advises that the free version is used in the same way that they co-install properly and work in tandem during normal operations without any obvious interference or resource drag. [10] This is a significant difference between Immunet and other contemporary antivirus products. [11]


While independent testing has been performed, PCMag, [12] in 2010, rated the product to be fair in its effectiveness.

Immunet’s virus is stored on the Internet and requires more information than is available on the computer. Cloud protection has been known to provide better protection and detection, on the other hand, and offline protection is not particularly good. Overall, the effectiveness of the Free product is average; citation needed ] the company recommends that users use the Free product as an additional protection, rather than using it alone.

In Windows 8.1 and 10, older versions of Immunet such as 3.x only satisfies Anti-virus protection and protection.
