I've had this virus before, and was able to get rid of it with a system restore and then do various scans.
However, this time, it deleted all of my restore points and won't let me into safe mode.
It tells me that "all activities of this computer has been recorded. All your files are encrypted. Don't try to unlock your computer!" And then a bunch of stuff about how I have violated copyright laws, and to get rid of this message, I need to buy a moneypak giftcard worth $300 and input the code in the next 72 hours or they'll file charges against me.
When I log in it immediately goes to this page, and if I go into safe mode [with networking or the command prompt, too] it starts to log on, and then reboots. I got to my system restore through the "Repair your computer" thing, and it said I had no restore points.
The startup repair detects nothing wrong, either.
My other options are:
-System image recovery
-Windows memory diagnostic
-Dell DataSafe restore and emergency backup
Ctrl+Alt+Dlt works, when I'm logged on as usual, but if I try to open the task manager or anything it just goes to the FBI screen.
