Re: Windows messenger and UpnP security



Greetings Stefano,

No. The ports are opened and forwarded when the conversation starts and removed when it
ends. As well, they're UDP ports and if you had a trojan or virus on the system listening to
these ports, Messenger wouldn't chose those ones anyway as they'd be in use. So the answer
is no.
