if you're worried about things on your machine or information being taken, theres a simple way to stop everything including downloads. create a fake user on your machine. i tend to use the name "internet". make him a limited user with no rights. now load you software from your adminstrative account, but otherwise use your internet account to play the game or just cruise the internet. should something try to load, it will not be able to, because that account(interenet) has no rights. is a cheap security tool, but it works well. ive done it on many of my customers machines and hear from them less after i do it.
