FBI ATTENTION...locked out of one of my pcs and that one runs Windows 8 Pro. I went to Johnnyguru.com and I suspected something was going on that was funny. I got some strange pop-up while there and didn't catch it when it appeared, it was too fast. Next thing I know I get this goofy FBI lock out- my pc's blocked screen. And they claim I need to send money to someplace called MoneyPak. How do I get into Control Panel to remove this file from start up again, BEFORE the damn machine locks while trying?
