bt.. what is this doing in the bot/hack/guide section?? o0
the safest thing is to format your pc and reinstall your operating system.
after a fresh formatation, install an good antivirus (avast home for example) and then install the rest.
make sure you scan EVERYTHING you download at

.
ah..before i forget.. after having a clean system change your passwords from silkroad,msn,icq and so on...
