Hmm, yeah, don't download bots, especially from people you don't know. The STS bot downloads a keylogger onto your computer, I believe. Try running Ad-Aware and see what it comes up with. Never having dealt with it personally, I don't know of any keylogger removers that actually work, but maybe the keylogging section of

all of your passwords. And from now on, whenever you enter passwords or credit card numbers or anything very private like that, you might want to use the On-Screen Keyboard.

I hope this helps in some way. Let's hope that whatever you deleted has helped. If you're really that desperate to cheat at an online game, try getting familiar with Tsearch. Heh.
