clan page virus attacking

dear z8games recently i discovered some problems visiting clan sites i always get 8 virus attackings when i try to visit clan pages (internet explorer) with firefox there is no problem, this doesn't depends on my virus scanner (avg) i already heard of 3 other players they found the same problem and they didn't use avg and used firefox as internet, so can someone tell me he has the same problems or its it just us 4?

thanks
