Recently had a computer get a blank screen, on reboot it would loop in the Windows 7 Professional (64 bit) startup repair utility. I was unable to repair from an image so I had ordered the Reinstall/Repair disks from HP. While waiting, I googled the error and found symptoms similar to others who had a rootkit virus and they mentioned getting to the desktop by choosing the boot option of not verifying signatures and then cleaned the virus with TDSSKiller from Kaspersky. Those suggestions worked in our case and TDSSKiller found the infection in MBR0. Program said it was removed and I did an additional scan with MSSE ( MS security essentials) and everything looked good. Her computer shut down over the weekend for windows updates and on reboot the virus was back. I followed the same procedures but I believe the malware/virus is still residing in the master boot record. I need some guidance on additional steps to clean it up, thank you.
