Grisoft has developed quite a following with its free (for personal, non-commercial use) security applications, and for good reason. AVG anti-virus and anti-spyware programs use little overhead and have proven effective at combating common malware. The security products have racked up a number of awards and accolades as a result.
Now there’s an anti-rootkit utility in AVG’s free software stable, too, and for users seeking a minimum of interaction, AVG Anti-Rootkit Free may very well be the Right Tool for the Job.
