I have set the Norton Firewall to ALWAYS ask me even when low-threat apps attempt to connect to the internet. Today I see a whole bunch of programs that were set to allow access when I was away from the PC overnight. So the firewall is disobeying me. My system was hijacked a few days ago by someone using Teamviewer for remote access and no I see that one of these rules that were allowed when I was away was to allow the TeamViewer service to access the internet. This is terrible. What is going on here???
