ok
i found other 2 trojan-gen and i deleted them.

then i went out… and my father phoned me: just another virus alarm… i said: just push repair… suddenly my pc internal speaker started to play like an ambulance… i could hear it by my phone!!!
I said: dad turn off everything

now i’m at home
i’ve just finished a scan with avast and everything is ok, the same with “The Cleaner” and ad-aware 6.0
now i’m scanning with the freeScan at http://us.mcafee.com

what happened??? ???
