I was looking at some of the users profiles on the boards. Suddenly, when I opened the page of a guy named "TheCollector", this happened: I guess you all understand, but in case you don't, since my Avast is in Portuguese, it says: "Malware blocked - The internet module of avast! blocked a harmful web page or file." I looked it up in Google for "TFW2005 virus" and the first result was seemingly to some thread in TFW2005 named "Internet Virus Warning", but when I tried to open it, the page was also blocked and Avast showed the same advice as before. I tried navigating around TFW and getting to other threads and user profiles through Google, but none of these get blocked or display the same warning. So, it might be something from Internet Explorer (I know, I shouldn't be using this thing for now) or, most likely, just a false alarm from Avast, but I guess it's important to report this anyways.
