Figured it out. There was an old AntiVirus on the system called eScan Corporate Edition 2006. I didn't realize it was there because instead of uninstalling it, someone just disabled it in msconfig. It had a password on it that the customer did not know. So, I contacted support at
http://www.mwti.net and they directed me to a password reset utility for the software (
http://mail3.mwti.net/esreset.com). Then, I was able to remove the product with Add/Remove. Deleted the escan directory and Cleaned the registry with ccleaner. One of the PCs had traces of Norton left on it as well, so SymNRT took care of that.
Normally, Avast will throw a fit when I install on a PC that has another AV software installed. Maybe Avast can be improved to look for not only active AV software, but the leftover traces or disabled AV software that might cause problems like this??
The two PCs are running perfectly now. Avast alongside Malwarebytes Pro. They make a great "malware" tag team.
Thanks for the help. I wanted to post my findings to help others in the future.
