>>>>>Thank you also for the links. It looks like RegScan.exe could be a legitimate program or a trojan. I have already downloaded and ran UniBlue Registry booster. It found some 500 errors in my registry. Right now I am deciding if I should purchase their program to eradicate the errors (and if in fact it will help with the RegScan.exe problem) or to leave it alone for now.

Make sure to use new media for your new backup. Do not backup over your only other backup, if you get my drift :)
