I've had my share of problems with multiple commercial anti-malware programs which either detected false positives (McAfee's quarantine of XP's svchost.exe comes to mind) or claiming they found something but were unable to do anything about it. And Websense which blocked the local newpaper site for a while. For RogueKiller, WOT did not flag the site, and a scan of the downloaded program by MBAM and MSE and Norton found it clean. That said, I tend to err on the conservative side, and the BSOD report below is not comforting. I probably will, however, keep it around for worst case problems where nothing else has worked.
