Regardless of how many times I check “Remember my answer” I will get at least 2-3 firewall notifications that some Microsoft product is trying to access the Internet. Most often it’s HxTsr.exe. How can I set firewall to stop bothering me about MS programs? >:(
Might be best to confirm your avast firewall settings are set to default, as in the attached picture below.
To ensure new settings take and run as expected, reboot system after making your changes.
Protection>Firewall>Settings>Policies.
