Hello,
this is due to the ads.
it looks like there were an add, pointing to an infected site. (this should already be fixed)
@chompy has to go to the webmaster-tools of goolge and request another review - otherwise this will probably vanish within the next 90 days
it will probably only affect google-chrome users. But the only thing we can do is waiting for chompy to request another review by google - or we have to change the thread somehow (so that it will get another id)
