Well.. maybe try to trust people here then ?
This forum isn't some kind of random crappy place with porn like you can find elsewhere, it's a pretty serious forum with lots of people only wanting to help, if someone here try to give you a virus by making you download something bad you can be sure he will get banned quicker than it took me to write this post
So if you have a link or advice posted here telling you to download something to make the game works, if this link have been here for months and nobody reported it, there is 99.9999% chance it's safe
