Great article, Mike. I'm not in the business, but I've had a few run-ins with viruses and spyware, and here's my personal low-cost, low tech solution.
As I'm on dial-up, a hardware firewall is not an option, so I'm using Zonealarm 4.5.594 free version. This is the bare-bones, firewall only version, with no anti-virus or other additional features. While this is a disadvantage, there's less chance of conflicts with other security software, and that is a major headache. The latest release of Zonealarm, version 5.0.??? has major problems, particularly with Windows XP. You can still download version 4.5 here.

The free version of Grisoft's AVG does the job most of the time. The only time it didn't was when the Opas virus was running wild. Zonealarm stopped Opas, after we installed it. This is a long story, but Opas doesn't come on emails, but attacks though unblocked ports, which are open by default in Windows.

Ad-Aware and Spybot are free and both are better than most of the expensive spyware cleaners. Ad-Aware is a little easier to use. Spyware and popups were considered a harmless nuisance at first, but some new ones are dangerous.

Browsers. Let's face it, Internet Explorer has more holes than your target backstop, and more are found every day. As of today, Mozilla Firefox is the most secure browser. The hole reported last week was fixed with version 9.2 on Friday, but it's still open in Explorer and Opera. Firefox is free, rather basic, and slower than Opera. Both Firefox and Opera have popup blocking and good cookie management.
I use Opera 99% of the time. The default setup is cluttered, but easy to customize and clean up. If anything there's too many features. It has problems with a few badly coded sites, but there's an excellent user's forum for sorting out problems. Opera has unobtrusive ads if you don't pay for it.

Hint. If you try Opera, make that large left-side sidebar disappear by clicking in the middle of the left margin. If you need it, click there again.
If you're getting tons of spam, get Mailwasher. I was getting over a 100 emails a day infected with the Zafi virus 2 weeks ago. As the emails it came in had a limited number of features, I was able to set up a filter and delete all of them with one click without downloading them first. That saved a LOT of on-line time.

I don't have any personal investments in any of these programs. These are only my recommendations, based on my limited experience, and not Beartooth Bullets. Maybe Marshall and Alex have some recommendations too. (Hint, Hint)
