HTML:Iframe-inf [Susp]

Hi, I keep receiving this threat alert every time I try to go to a specific website that is a reputable website.  When I use a different anti-virus program it does not detect the threat so I believe that it may be a false positive.  I even tried making this website an exception but it still gets blocked.  Besides disabling AVG, how can I get to around this problem?
