AVG and Microsoft Security Essentials

On an XP machine, had AVG Free installed and decided to change to Microsoft Security Essentials (MSSE). Uninstalled AVG with Add/Remove Programs and installed MSSE. That worked for awhile, until the first MSSE upgrade (not update) failed. Uninstalled MSSE, installed AVG 2011. AVG started throwing an error related to avgrsx.exe and MSVCR80.DLL.
Found out that AVG has become similar to Norton in that you need a removal tool (http://www.avg.com/us-en/download-tools) to completely uninstall it. In my case, the removal tool triggered a restart, then continued on to good finish after the reboot. I remembered one of the fixes for the MSSE problem was to completely uninstall any previously-installed anti-virus software and then try an MSSE install again. So I did.
Worked fine, running the AVG removal tool was the fix.
