Auto updates. The thing comes in as XP Antivirus 2012 and immediately scans the computer for supposed viruses then asks you to purchase the product to remove them. It has already infected by the time you see the first screen. It totally blocks mcafee from running and malware bytes as well. Got past spysweeper too. Then it changes and calls itself windows security center and shows up on the bottom tool bar. Can't get on the Internet can't run ,scans can't remove it. The only thing that has worked was reformatting and of course I lost a ton of saved stuff. Nothing that didn't have backups but what a pain!
