My firefox 3.0 reported that this site had been reported by google to have a security problem of some sort. I reported it to the owners of the forum. Lets not all leave because of this. It is most likely a false positive with their new detection systems. But I thought all of you should have a heads up.
Be very careful about downloading any file that cannot be tested by your AV.
It happened to me too, that's why I've been away from the site for a while. I don't know if the issue got resolved, since I'm a different computer now, and I get no other warnings.
