Popular free antivirus provider GRISOFT has today launched the first non-beta version of its AVG Anti-Rootkit software, which is free to all home users. Unfortunately GRISOFT does not offer support for this new product so you'll have to rely on their forums if you run into any problems, but you should certainly consider adding this software to your PC security arsenal. Rootkits are among the newest and most difficult to detect forms of malware being circulated at present, and most standard virus scanners will have either no rootkit detecting abilities or be very limited in their effectiveness, so at present the best way to combat them is by using these standalone rootkit-detectors. Other free anti-rootkit software to look at includes RootkitRevealer, Rootkit Unhooker, Rootkit Buster, IceSword and Sophos Anti-Rootkit, although some are difficult to use and may not remove the rootkits for you - as rootkits are still relatively new and different software will be better at detecting different exploits, it is a good idea to use multiple scanners to complement each other. AVG Anti-Rootkit will work on the 32-bit versions of both Windows 2000 and Windows XP, although Windows Vista support is not mentioned.
