I don't care price wise one program could be $3000.. what i want to actually now is which of these three programs would be better
...and by better i mean keep your pc safe from viruses/trojans/spyware , remove all that if you happen to get any, and NOt MAKE YOUR COMPUTER INSANELY SLOW =P

1. Norton 360 (newest one version 2.**)

2. Avg <--if you say this which one because i dont know much about avg
3. Mcafee
