i have a crappy computer with windows xp that i dont really care about and get all the random virus weilding stuff i want and can get rid of it easily with a system restore, virus remover etc... but i got this download and it automatically turned off my computer, when i turn it on it goes to a screen telling me to either go tto
start windows normally
start windows from last working state
safe mode
safe mode with command prompt
safe mode with networking
it will only work in any of the safe modes and i have run a virus scan (in safe mode) with avira free anti virus.
what can i do to get rid of this because i do not want to spend money to get a new hard drive.

-- virus details--
got from a farmville hack page
fooled by something like x-hack generator? i think that was it
