I run NOD32 and love it. I get multiple definition updates a day. and catches virus very fast. Im thinking of trying to see if I can get work to switch from Mcaffee to NOD32.. As for Firewall I run Tiny Personal Firewall.. I switched to that a few years ago from Blackice i think it was and/or Zonealarm. those just had too much crap in em..As far as I can tell Ive had no problems with Tiny.. but then again I dont pay that much attention to it..I just tell it yes let what I want through and deny everything else.. This combo I install on every one of my pcs..
