which script were you using?
did you scan your computer? it's not 100% that you were hacked by pb, maybe you got a keygen or something, even if you think you are not infracted, it could be.
did you just use pb? or also other bots?
did you save your account informations in the bot client?
did you save other account informations (then that account that got hacked), in your bot client? are these accounts fine?
i also use pb and never had a single problem with any kind of script, and i used a lot of scripts
