One of my friend, who's been known to take hacking as a hobby, a long time ago told me:
A virus is meant to be a pain in the ass and make you scream profanities over the top of your lung for pissing you off. By this definition, Norton's software suites are the most succesful viruses ever written in that regard, and people even pay for it! The guy who wrote that is a GENIUS!
Live and learn folks! Live and learn...
PS. AVG Free and AVAST are both free antiviruses suites that do well, and work as good or better than norton or mccaffee crap.
