I actually have experienced something of the same, especially with regards to the keylogger and so on that is probably on your pc. In my case it was a former friend that simply couldn't deal with the fact that I didn't want to have a sexual relationship with him. He ended up installing a rootkit on my pc and well needless to say, my pc was completely ruined. The only difference was, was that he quit wow and thus didn't stalk me there, but did proceed to stalk me everywhere else. Get that pc cleaned out and try and get a restraining order before things get worse.
