I just received a safe browsing warning when trying to open a topic related to www.isolutionclub.com while trying to open http://www.gamedev.net/topic/647913-release-code/.

I remember something vaguely similar happened to a different forum I sometimes read, but only to registered users with an extremely low probability. Since I only read that forum as a guest, it never really happened to me. That was a rather insidious infection of the forum software though which took quite a while to remove.
Edit: false alarm. After some more investigation the problem seems to be an image linked in that thread.
