My forum looks messed up since a short while, haven't done any changes at all. www.spagtv.com/forum the background is supposed to have a scanline, the fonts are messed up being times new roman, the quick theme changer doesn't work, font sizes are wrong, and some people can't log in. I saw some thing called orentraff.cn caused the problem so I googled it and saw that it is some weird type of virus, or something, I have no idea. Can someone please help me removing it? It is only affecting my /forum directory, so it seems. Admin CP works fine. I don't get any virus warning when entering it though, and my PC or anything doesn't take any damage.

nice fourm by the way if you think that there is a real virus on the sever if you have cpanel most have a viurs scanner run it but back up your files and database

are you sure its a viurs as the site look ok to me

I really doubt it's a virus.
I'd check your themes and templates first. Do they hold the correct values?
