Title: Main Calibre Program Blocked by Avast Firewall
Post by: HairyScot on August 10, 2019, 04:06:26 AM
(http://)All of a sudden Avast on my laptop has decided to block Calibre when I attempt to connect my android tablet as a wireless device via the wi-fi hotspot on my wireless adapter.
This is something that has been working fine for years.
Now I have to turn off the firewall to synchronise Calibre Companion on the tablet with Calibre on the laptop.
I tried setting a Default Rule of ALLOW ALL for the program but to no avail.
When Calibre is blocked "Host Process for Windows Services" also gets blocked.
I receive no error messages.
Windows Defender and its Firewall are inactive.
Attached pics show the Avast screens.
Any ideas or info would be greatly appreciated.

Set the Avast Firewall to private mode and reboot.

Set the Avast Firewall to private mode and reboot.

Makes no difference.

I have had to follow the path used by many others experiencing this problem:- Turn off avast firewall and turn on Windows Defender Firewall.
Guess who won't be renewing come February 2020.
