Forget about "suites" for "internet security". Assemble your own. There's not one manufacturer who does it /all/ just right.
I'm fairly happy with the annual Norton Anti-Virus program since about 1993. The rest of their "suite" just sucks goatballs and wreaks way too much havoc upon unsuspecting computers. For a firewall, I'm using a Netopia Cayman 3546. Pop-up Stopper Pro is fighting pop-ups, and Spybot Search and Destroy and Ad-Aware share the task of eliminating spyware, malware and adware.
I wish there was a manual for fine-tuning Windows though, but in general, you can even keep it safe. Ditto for IE 6.
For those who are going to say, "Use Linux!", I'm using Windows since version 3.0 and I'm sure as hell not going to throw away more then a decade of experience. Incidentally, Linux takes as much time and knowledge to configure it to be useful and safe as WXP, if not more.
Use your favorite search engine to find the programs mentioned above. As for the router/firewall, my ISP is offering it for $378 +S/H, +sales tax, but I found one, two weeks old, on eBay for $55 incl. S/H, no tax. Original buyer just wasn't smart enough to figure the thing out, and admittedly, it took me a whole night as well.
