Hello Guys,

                 I have found out this application called ULTRASURF,which bypasses all possible firewalls.

The native firewall on vista is able to block this application & some software firewalls as zonealarm are able to detect it

 

It works on tcp port 9666,but just blocking this port doesn't help as it work on both port 80 & 443.

it also uses a lot of open proxies which are:-

Any updates as to how do we block this,its giving me sleepless nights as keep thinking of ways to block it at all possible times.
