How to hide Ports 20/21/500 ?
Hi All,
Win7 starter, Acer netbook.
Shielddsup at GRC.com shows Ports 20/21 and 500 are visible to the internet.
Should I worry?
How can I hide them like the rest of the ports?
I tried changing Firewalls from Private Firewall to Comodo, but still the same results.
Thanks
