i have this problem for 2 weeks already. drove me nuts.

it'll disable my internets and media but only after i closed the error window. if u leave the window alone can still use like normal.. i tried this solution instead.

it's called Windows Worms Door Cleaner. what it does basically is block all the ports that are vulnerable to worms exploits. The thing with windows is all ports are open by default whereas in Linux all ports are blocked by default.

problem all gone for me!

a solution if u guys are still stuck with the problem..
