http://en.wikipedia.org/wiki/MS_Antivirus_(malware)
its not a virus, and it's quite simple to remove really [unless you only have access to a usb keyboard and legacy usb is turned off in your bios]
if you follow totally randoms suggestion up into the point where you get access to folder on C: [or any other method of accessing the filesystem] but then go in to program files, find the folder for the fake anti virus and delete it, then boot normally and do spyware scan immediately
