|That's a very bad one. Only program I found to remove it was Malwarebytes Anti-Malware..|
You'll probably have to download it using another computer, then use a USB drive or burn to CD to transfer to the infected computer. Then try installing and running it.
Be aware, even though I got rid of it before using it, sometimes the damage done by the virus is so bad you may still end up reinstalling Windows if it doesn't work right. Good luck.
