Jscher2000 thanks for your reply! No it won't let me download. Well, I can download & run, but during the verifying stage it interrupts the program.

That is a very nasty rogue anti-virus/security program. It is probably running in the background on your system and intercepting/interfering with .exe applications. You can read about it here: http://www.bleepingcomputer.com/virus-removal/remove-win-7-internet-security-2011

Helper7677, thank you for your help. I was locked out of my e-mail by the virus. I fiinally did a restore to a week ago, and now I'm back. Do you think I'm still infected?
