As for myself, I have my "Traffic Controller" set to Monitored. Just a step tighter than "Smart Access" Then I leave it up to McAffe to accept,or not to accept incoming connections. It still allows McAfee to make recommendations.
In other words, I allow McAfee to decide what can connect,and not be allowed access.
So far after (10) years plus, the only virus I have incurred, was the "Eicar Test String" which I initiated myself,to periodically check my Anti-Virus. It is a "Benign" application that is available to everyone.
Hope this helps.....
You can always view your "Security History" to see which programs have been denied access.
Please continue with that original thread, thanks.
