norton is garbage and a hog, only their SAV line of products are good and even then only versions 10 and before, even 11 is a hog now like its NAV cousins. the best protection is Kaspersky for antivirus, they're very highly rated... but a hog too i find. the best balance? NOD32 from eset. super light and super effective. really good product. for anti spyware? that's a crapshoot, you'll always find that certain ones catch certains things.... super anti spyware is good, avg too. just don't click yes when that pop tells you to
