UPDATE 3/22 9:00pm: We've finally gotten the all-clear from Google. You should stop seeing warnings soon. It may take up to 24 hours for the changes to filter through web and out to individual browsers.
UPDATE 3/22 Noon: Google is recrawling the site now. Hopefully this will be fixed by later this afternoon. Cross your fingers, folks. This has really been annoying since we never had any damn malware to start with - another site did it and we got the punishment. Argh!
UPDATE 3/22 12:30am: This is f--king annoying. We're waiting on Google to allow us to request that they recrawl the site and realize we're not hosting viruses and whatnot. No kidding. It doesn't look like they're going to allow us to request the re-determination until Monday morning. The other services all say we're clean, so we're just waiting on Google to recrawl the site now.
UPDATE 3/21 11:30am: The problem continues. We've found what appears to be the problem. Our ad server for our self-sold ads was used a couple of weeks ago to serve up malware on another site. Since we use the same software, Google has blocked TBP and reported it as "suspicious." (Not "known.") We've removed the software and are waiting on Google to re-evaluate the site again. No idea when they'll actually do it though. :(
Several of you have been reporting a Malware warning appearing when you try to visit certain pages. We're working on it and it should be cleared up soon. My apologies to everyone.
It was coming from one of our ads. I've notified our ad providers and asked Google to remove us from the notifications. It's now just a waiting game.
I'm not getting the warnings now, but it also depends on which page and which ads get served up. It doesn't seem to happen on the front page of the site or in certain browsers, for example.
If you get the warning, leave a comment and let us know what page you were trying to visit. We want to make sure Google doesn't keep any pages flagged over an ad that popped up once.
