GRC Shields Up All Ports Scan Results

Hi,

 

I have run the Shields Up scan on a computer connected to two different networks (different ISPs, different locations).  Both give the same results - port 443 is open, 70 ports are closed and the remainder are stealthed out of 1056 tested.  This is pointed out by GRC as a vulnerability, in particular port 443.

 

Without Freedome, all 1056 ports are stealthed (ie no vulnerability).

 

Can somebody please shed light on what is going on here as there are some old posts that ask variants of this question and the responses are very cursory?

 

Thank you.
