The xenonauts.com website has been hijacked. I don't know whether this site is on a separate server, or the same server as this forum; so there is a potential that your user data for this forum has been compromised, too.
I've notified Goldhawk Interactive about this problem in January; but to this date, nothing has changed.
If you look at the source code of any page on xenonauts.com, you will notice that some content has been inserted before and after every page. At the moment, this seems to contain only spam links, but harmful content could be added this way, too.
