It doesn't always come up. I'd say about 10 or 20% of the times I come on the homepage I get that site redirected and have to close my broswer. But it only happens on the homepage of mmaforum.com
So I'm thinking it might have something to do with my pc, or one of the adds on the homepage since the adds change. And I'm thinking one of them might be redirecting systems.
Of course if it doesn't happen to anyone else I'll just reformat my pc since I haven't done that since I got vista over a year ago.
Here are screen shots of what happens.
Get on this site only, and sometimes the page gets redirected and here are some screen shots I just took because it just happened recently.
