If a school told me what I *need* on my system, I'd tell them to go piss off.

You guys know you can disabled that, right?
PC Magazine is currently choosing Norton 2010 as its editor's pick for security suites, claiming it blew away the competition. Kaspersky and BitDefender had noticable impact on system performance. "ZoneAlarm Extreme Security 2010" now offers harddrive encryption, which I thought was interesting. (I use the free firewall)
I use Symantec (not Norton), good on-the-fly detection and relatively small footprint with little or no performance hit. I tried Nod32 a few years ago after seeing it mentioned on the forum, and I couldn't stand it. The file-scanning/protection was tremendously slow making the system practically useless.
I just read about
Prevx, which is new to me, and it sounds promising as an anti-malware tool.
