Does the forum have a security problem?

When I visit the forum Firefox is showing strange 'loading from' urls. This only happens for http://www.opendcl.com/forum/ not for any other websites I visit. Nor does it happen for http://www.opendcl.com/. This morning the 'strange' url was something with 'tallamadera' and now it is 'koeppel-kindschaftsrecht.de'. I'll try to check things at my end, but I suspect there may be an issue with the forum.

Yup, we got hacked. Should be all cleaned up now.

OK, Thank you.
