Nice post and list, good job I guess, with the list compile anyway; However, I don't agree completely with the "Users" poll of choice, and even the editor's choice for that matter, For example... Look at Ad-ware, with the claim that it is such a great "Antispyware" saying, "Winner: Ad-Aware SE Personal. First off, that's if that stuff got into one's PC in the first place, because of poor protection! Secondly, "Spy-bot search & Destroy" will find more then spy ware, broken links, Lock Host files, prevent browser start page changes from malware, and Tea Timer which let's one know if a program is trying to change the PC's registery, but not limited to, new start up programs even from malware and spybot has resident protection, which one has to pay for in Ad-ware, and when combined with "Avast" I have protected all my PC's resulting in "Zero" infections, since Windows 95 came out. Spy-bot contains more selective choices for savvy users than Ad-ware ever did, and Avast has "Real-time protection" that one has to pay for in Ad-ware, Between Avast, and Spy-bot with it's "Tea Timer" both have real time protection, and nothing gets in, I also use Javacool's Spyware Blaster for real time protection for browsers in Explorer and Fire Fox. As for my fire-wall, Nothing but Zone Alarm's free fire wall. Lastly, I suppect the electors are not very savvy with PC's if their selection is Ad-Ware. In todays world one has to run many programs that over-lap the protection for the best results, and the programs I recommend do just that, that's why this article is not doing justice for the novice PC user, these editors need to show combined programs, not individual results. Also, One can run Ad-ware behind Spybot, because as in all software, one company may have an update lag.
PS. For the remark, " I also experienced an irritating interface glitch that obscured the buttons on a dialog box asking me (presumably) to allow or deny a change to a Registry file." There is a fix for that on the old version you ran, version 1.4. But if one is not savvy, they would not have known.

Spybot version 1.5.2
Avast version 4.7
SpywareBlaster version 3.5.1 (I also use on Vista with no problems)
ZoneAlarm version 7.0.462.000 (I liked 7.0 best)
Linksys, Nat router (Perfer no UPNP, also protects "0" port)
