That is one intensely rude awakening. It is disturbing that these sickos don't care who they hurt so long as they can satisfy their deviant perversions. If you are certain you have nothing illegal & incriminating on your hard drive that you yourself brought in then I would highly recommend that you contact a watchgroup like the folks that do those Dateline "stings". I think the group is called "Perverted Justice" and you should IMO contact them immediately so they can seek out the individual(s) behind this and also show your speedy response in clearing yourself from any ties to this unfortunate situation. Doing "nothing" about it and hoping it will just go away may not be in your best interest.

Sorry to hear of your situation and good luck in the "clean up" process.

Peace to you.
