Computer all messed up

My computer just quit working the other day. I got the blue screen saying it was infected. I shut it off for a day and today it worked for awhile but now when i restart it all it does is go to a screen saying Loading PBR for descriptor 2...done. Thats all it does wont go to any other screen. It wont let me go into safe mode.

I assume you have a Dell ?.....It's simply loading the Image Restore Partitions. If you press CTRL+F11 when you see www.dell.com (you have a 2 second window) it will load the Restore screen. However, if don't want to lose your data and revert back to factory defaults, don't continue with it (Don't worry, it won't just RUN automatically if you hit CTRL+F11, it will pop up a Window) It's an informational message only. Also check that there is no USB drive plugged onto the USB port while restarting the PC

I try the ctrl f11 and when I hit to restore the computer it freezes there.

I can safely say that this is not a malware problem.All I can surgest is that you do a reinstall Windows.
