If you honestly beleive this is true, how about this for an idea....

Do nothing with the probelm pc - Go to a cyber cafe or whatever (buy a new machine) for your internet access & use the 'problem' machine for a little social engineering.

Send an email suggesting that you've been having an affair to a willing accomplice (you can use me if you want) & wait for the response.

Use your imagination & by the time the divorce gets to court you should be able to make a lauging stock of your ex.

Or you could jsut call the feds.
