I just installed AVG antivirus on one of my computers, and for some strange reason its detecting Hijackthis 2 beta as having a virus.
Of course this is just a false positive, but I wanted to give you all the heads up if your using AVG.
I just love how AVG "heals" files, it merely moves them to the Virus Vault without saying too much, then again that's the first detection I've seen in v7.5.
