What is your OS ?
Do you have a USB keyboard ?

There have been issues in XP when using a USB keyboard, the keyboard may not be recognised before windows starts.

Deletion isn't really a good first option (you have none left), 'first do no harm' don't delete, send virus to the chest (a protected area) and investigate.
