Most keys and the usb ports dont work

[afreddy]

I am using windows XP. I had a trojan attack (trojan generic and worm generic) post that the three usb ports dont work and most of the keys dont work either. I cannot even use the keys to get into the bios

Please help

scan your system with powerful antivirus such as "Nod32" and "Avast Antivirus" also re-arrange usb cables on mobo.
go to bios and enable usb support.
