Have you received the new fake FBI virus floating around recently? The virus hijacks your system and turns your screen white. It disables all the normal hotkeys to launch task manager, etc. Basically it cripples your computer. Even safe mode with networking doesn’t work. Follow the steps below to fix.
If you have a 2nd user on the computer, try logging in as them. If you can get in, then install and scan the computer with Malwarebytes.
If you have restore points on your computer, simply restore your computer to an earlier point in time.
If neither of the above options worked, head over to the Malwarebytes Forum and follow gringo_pr’s instructions. http://forums.malwarebytes.org/index.php?showtopic=123342
He will have you download the Farbar Recovery Scan Tool and then post a log file. Simply create a free account on the Forum, run the tool, post your log and one of the Malwarebyte’s experts will respond with a file to fix your computer. They are very knowledgeable and fast to respond.
