Do you hear your PC dialing out when you're not even trying to connect to the Net? Do you hear mysterious touch tone digits being dialed at 2 in the morning? Are you wondering perhaps if there is a ghost in your machine? (btw, if interested in a thought-provoking book, check out 'The Ghost in the Machine')

Well, it's not a ghost, but it could very well be a trojan planted on your PC that dials out to "premium" phone numbers (i.e. 900 numbers, international unregulated high/per minute rate numbers, etc.).
You get stuck with a nasty phone bill at the end of the month and the trojan author sits back on his/her PC and smiles as the bucks roll in.
