Norton is one of the WORST I have EVER used... after countless virus related problems and having to learn how to remove them manually over and over my uncle showed me Kaspersky.
I freakin' LOVE Kaspersky... totally owns.
Some say it isn't the best out there... but it has detected EVERYTHING it has come in contact with... including some things I have made to try and break it.
One thing about Kaspersky you may call a plus is that you can easily find a "License Key" to get full access to the program without paying...Especially on UseNeXT - the God of all things downloadable.
Disclamer: Having full access to Kaspersky without paying is illegal.
blah blah blah....
