Too old for this shit!
Process explorer is also a handy program to have.
McAffee is the reason cyber command gets hacked.I use Avira and spybot s&dFuck Zone Alarm. Seriously I had them for a long time, I mean, like 4 years and they've done nothing but go downhill. Go with BRiT's suggestion and get Nod32. I have Mcafee but only because it's free for military personal, if you're going to pay for it, make it worth the monies.
After working with Symantec AV Corporate Edition and Norton AV.... no. Don't use that crap.Otherwise use Norton 360 (despite the reputation they righteously gained for slow performance, they have cleaned up their act in the last year and are once again worthy of installation).
I'd rather have a free antivirus; I've been using AVG for 4 years and I've never been infected. That said, AVG uses way too much memory and it becomes a problem with certain games. I think Avast is also free, and I read somewhere that it uses less memory. Would you recommend me switching to Avast?Never ever ever use Symatec or Norton AntiVirus. They are absolute crap.
As stated already, use Eset's Nod32 or Kaspersky. The combo listed "AVG Free and Microsoft Security Essentials" isn't that bad, but are second rate to Nod32 / Kaspersky.
