I found an App called UltraSurf. The App listens on port TCP:9666 on
127.0.0.1 and XP Firewall does not block the software. UltraSurf starts a
"proxy" and bypass proxies opening TCP/443 conenctions with proxies arround
the world (mid-east and Asia)

In Vista the native firewal blocks the software.

How can i block the software? Using SRP is not enough because there are
various versions and the software auto-updates and changes the hash and there
is a "portable" version, so, the Path Rule cannot be used too.

Wich client-solution i need to block the UltraSurf from bypassing my proxy
(Linux)?

The IPs i found, of open proxies used by UltraSurf
