I'm not as swooft on updates, etc. as I need to be. I discovered an infected item on my pc and deleted it. I have a cable modem connection and am using win/98. I upgraded Mcafee, got a personal firewall, jammer, and lockdown, and adaware. I also use uptodate defense programs in VP.

How much of this is necessary? I've done online scans for trojans, bo, stealth, etc., and they all say I'm in excellent shape, but am I? Am I just wasting valuable space?
