I have Emsisoft Anti-Malware and Online Armor Firewall (latest editions) installed on my computer.

I performed Shields Up test at https://www.grc.com/x/ne.dll?bh0bkyd2


The results were not good: 8 ports were not stealthed.


Is it possible to fix this?


Thanks in advance,




Here is a mummary of the test:

Unless you are connect directly to the Internet without a router/firewall type device like a Linksys or D-Link etc, this reflects the status of the router. I presume that you are like most and have this router/firewall between your computer and the Internet. I would logon to the router and see if it is doing some sort of port forwarding and to which IP.


The fact that they are closed is good. GRC probed and probably got a closed response. NOT good.


By default all those ports are blocked by any firewall that I have ever heard of. As a matter of fact all unsolicited incoming traffic is blocked by default or else it is not a firewall but just a router.


Ports are opened automatically by the fireall in response to an outgoing request to an Internet IP but only for the return traffic from that IP.


Or it is opened by configuring the FW to let it through.
