All of a sudden I got a security system alert saying I had problems. It is Windows 7 Defender and they won't let me do anything with the file extension of .exe. I went to safe mode and can't start any programs at all. I know that Malwarebytes can remove it but I can't download Malwarebytes because it has an .exe file extension. All virus/spyware programs, or any other for that matter, can't be started. As soon as this hoax sees the .exe file, it brings itself up. Anybody got any good ideas? Thankfully I have a separate computer to send this from.
