Shilo Hi.
You say!!
"Kerio firewall and AVG installed." ? are they both working at the same time?
It not good to have two firewalls running at the same time.
Im sorry I dont know Kerio so I cannot tell you whitch one to use.
(People feel free to offer sujestions)!!! what is best.
Dont uninstall yet, Just try turning one of them off. Restart L/W, then in L/W
Click on View/ShowHide/Connections. that will now show your connections page for easy access. You havent said so, I am prosuming you see a wall in
front of the globe, bottom left of L/W page,
After you drop one firewall, the wall should go, if not try changing round to the other.
Oh!! nearly forgot What java are you using.?
Tell us how you got on.
Peace.
