While anti-virus and anti-malware is not much of a problem on Linux at this time, AVG has added this anti-malware protection to their Linux security software. AVG has supported Linux for sometime when it comes to virus and spam protection, but with version 8.5 they have expanded their anti-malware support. Besides that there are also many other improvements to the AVG Linux support like a new anti-virus filter, improved system resource handling, multi-core CPU support, and a new virtual file-system.
AVG's Linux software is compatible with all major distributions and will also work atop FreeBSD. The free version of this new AVG Linux update can downloaded at AVG.com
