Latvian. Ok. Sooo....where'd that come from?
If it is a hacker (And not some twelve year old who has nothing better to do, which really is a possibility) I don't think you can track them. And handling virsuses is really dangerous work--I know a guy who handles viruses(Computer reboot viruses, he aint anything special but a real jacka**) but don't mess with revenge. It'll come around and eat you.
