Viruses\programs CANNOT be spread through JJ2. It is impossible. There is no way for executable code to be transfered through the game. The closest that could come to a virus spread through a game is a level that has an AV in it.

This has got to be a program. And people have even said, that they observed symptoms of the virus after using a program.





And what I said about executable code being transferred through JJ2 is not completely true. I know how to do it, but it can't be done through JJ2 (A program could be used to mimic a JJ2 server, and send a program instead of a JJ2 level, and then disconnect itself after sending the program). If this was the case though, it could not be done unknowingly by the host, and would require the client to rename the file to something with a .exe extension. Also, if this was the case, the server would not be joinable and playable.
