Thank you for your help,but this is too complicated for me.
As you can see from one of my previous posts,I used Firewall App Blocker
to easily add outbound rules for apps.Webshieldfilter.exe tool is out of my league.
I never used any command line tool before.I hope in the future,Avast will fix problem
with Web Shield and Windows Firewall.
Again,thank you for your help.
