Your AV software should have no effect at all, it's the firewall
that is effecting the problem.
I also would note to site admin that contribs wiki and forum are effected
and only contribs website, have no problems on other sites.
I'm seeing the problem with IE, FF on XP & Vista.
Changing firewall setting has no effect, disable fw works to fix the problem.
I can access my own sme wiki without problem.
This very well could be turning people away from contribs.org
