Good antivirus progs: PC-Cillin, Panda, Node 32, Antivir (free), Kaspersky, etc. I've heard that AVG has slipped a lot lately in terms of relative goodness. Use only one. I use PC-Cillin (TrendMicro.com).
Good firewall progs: ZoneAlarm, Sygate, Outpost are all free for personal editions - if you are on broadband internet 24/7, buy the Pro versions. Use only one! I use Sygate.
Spyware blasters: I use both Spybot Search & Destroy and Adaware.
And one of the best things is to use some other browser than IE whenever possible. I use Mozilla as it is integrated browser/mail and news manager/HTML file editor/etc. And I'm used to the Netscape/Mozilla family as that's what I've used from just about the beginnings of the web as we now know it. There are some other good ones like Opera - it's just a matter of preference. Any of them are safer than IE even with all of the patches.
. Of course there is always Linux, etc. Then you wouldn't have to worry as much about the above.
