I am looking to do a destructive system restore on my computer. I seem to have a big problem with a trojan on my computer that I got off limewire, it has infected system 32 and when i start the computer, it sends hundreds of windows at me, so it is near impossible to do anything before start up. I have the disks in order to do the restore and I heard that if you press F1 key at the start up screen it will bring you to the BIOS but it doesn't seem to be working, and if I hold F11, it will bring me to a black screen. I needed to know a possible solution before bringing it to an expert or having to get rid of the entire thing. Please help.
