I'm not naive! I'm trying to be much protected as I can be. For example: My computer is disconnected from net all the time. ONLY when I need to go online, I'm allow it! Over the night, my modem is disconnected, my computer is without power.....those kind of things. All together I'm doing what I can to make me SAFER. Avast firewall is not real firewall after all. They (Avast) let ANY incoming and outgoing traffic go thru, without people to restrict WHAT and WHO enter computer. I'm not talking about applications (installed programs), I'm talking about NETWORK traffic.
