For example if it's in the tree that blocks sites, then it's not an infection but a protection.
I find a lot of folk start blasting away at the registry before they do more research.
I found a folder called "Trolltech.com" in my registry and was promptly informed by a friend that it was a virus/malware. Is this true? My antivirus didn't catch it and neither did Spybot or Malwarebytes... what do I do with it?
