I was innocently looking at the Terraria forums, when suddenly the window closed and I learned that "Win 7 2012 the security program" was not turned on. Apparently, this was supposed to be involved with windows, although it was unconvincing, as it expected you to pay money for it, and windows is famous for its free and AWESOME security programs. Anyways, I have reason to believe this virus came from the signature of another player on the forums, because I was on a topic at the time. The virus did hit my computer at the time that I was looking on the forums, and the forums obviously are not dangerous, so I'm sure it was in something else: a player's signature. Just a heads up to other forumers (stay away from the topic "One and one seventh week aniversary Terraria"), it may be possible for you to get a virus from the sight (my computer is fine now fortunately). If there is not already a button that allows you to block signatures, I suggest that the developers make one. Thank you for your time.
