That's a bit paranoid sounding. I don't run a software firewall or anti-virus now, but I am behind a router. I use Opera. I use torrents, not various p2p. I don't open unknown e-mails/attachments. I don't accept unknown users onto my contacts list. I clean out my system daily with CCleaner and jv16 PowerTools and I've used nLite. The main point is, you don't need system-heavy software to keep yourself secure, just a little computer-sense. Get a good hardware firewall. if you want a software firewall, get Outpost Pro v4.0. If you want anti-virus go with Kaspersky or NOD32. If you want freeware anti-virus, go with AntiVir or Avast, not AVG.
