That's what mine is. Avast! says that it has the Vitro virus, and from my understanding it infects all my innocent files. I figured that since all the files it's blocking are trusted programs, that they're false positives, but it's possible that it has infected the programs. (granted that they marked as JunkPoly files, and not Vitro infected files) Regardless, I'll run a boot-time scan and quarantine all the infected files. A boot-time takes hours to finish for me, but I'd rather have 5 extra bucks on my electric bill then have my computer fry. I'll post a reply tomorrow morning, but this still doesn't explain why the site is being blocked.
