|because you cannot access the PC in regular or safe mode I would suggest you physically remove the hard drive and slave it to another PC via usb adapter. Google that and you will find many different priced adapters from approx $8 and up.|
Once you slave it to another PC, do a virus scan and also malware scans on the infected hard drive. Once you remove those, pop it back into the PC and you should have access to your computer.
Some HELP in posting on Computing.net plus free progs and instructions Cheers
