Ried, I have the program "XP Repair Pro 2007" (
http://www.xprepairpro.com/) which is a system optimizer. I run it maybe once every month to repair registry errors. When it's executed it generates those XP Repair Pro entries.
Regarding IE7, I upgraded to IE7 from IE6 just before posting this issue in this forum in the hope that by upgrading to IE7 the issue would be resolved, but unfortunately it didn't, that's why I posted the problem here.
Let me know if you need any further scans/logs, etc. Thanks for your efforts.
