I rebooted and expected to see "Windows Security Center" of Windows XP warn me that there was a problem with my antivirus protection. I received no alert at all! I used regedt32 and deleted a handful of leftover keys from my AntiVir installation, but that made no difference.
Next I ran Belarc Advisor to see what it would report. Belarc said that my Antivirus was running and up-to-date! In fact, Belarc said that Norton 2004 antivirus was running!
It is true I still have the utilities of Norton SystemWorks installed (for the registry cleaner "WinDoctor" as well as other utilities), but I removed Norton Antivirus over 2 years ago. I went to Administrative Tools > Services and found 4 Symantec services listed. I disabled and stopped the 3 Symantec services that were running, but still no alert from Windows Security Center.
A little Googling brought me to the following webpage which gave the solution to this problem.

When I was writing my reviews on how to uninstall McAfee and Norton antivirus software, I noticed a problem with my laptop. After I had completely uninstalled both programs Windows Security Center and Belarc Advisor reported that I still Norton, McAfee, and my original antivirus AVG installed on the computer.
I proceeded to double-check the programs running in the background, programs running as a windows service, etc. and could not find any trace of these antivirus programs on the computer, but Windows Security Center reported they were still all installed.
It seems this issue appears if the WFI repository folder is not thoroughly deleted during the uninstall process of these programs. Follow the instructions below to delete this folder's contents and restore order to your system again.
