Thanks....I ran 3 spyware programs and they all came up with nothing except the Wild Tangent one, which I read is ok and needed for some games.
I read your suggestion about reading #7.
When I Open task manager (ctrl/alt/del) open the processes section, there is no RegCheck.exe to delete. It is not there.
I defraged my hard drive using Windows utility and then Norton Speed Disk on all drives.
I still get the same message when shutting down or rebooting.
I will try try preventing it from loading on start-up and see what happens.
Thanks for your help......Brad
