Avast Free Antivirus blocks Google Sites on Firefox

I am facing an unusual issue with Google websites on Firefox 108.0.2 (64-bit) since Avast’s 12/22 update (22.12.6044 (build 22.12.7758.769)); all Google websites are throttled or completely blocked because of Avast Free Antivirus Web Shield.

What I tried:
1-Opening FF in troubleshooting mode.
2-Using another profile with FF.
3-Refreshed FF installation.
4-Uninstalled then reinstalled Avast Free AV.
5-Used Avast Clear Clear to uninstall then reinstalled.
6- Added exception for FF in the Exception section.
7- Added an Allow-All rule in Avast Firewall for FF.
8-Disabled Avast’s Firewall.
9- Disabled Avast Web Shield (WORKED)

Note: All Google websites work seamlessly on Google Chrome.

For those who might face the same problem:

Apparently. I found a solution. I changed my DNS server from Google’s 8.8.8.8 and 4.4.4.4 to my ISP’s and viola; all Google websites load normally after a system reboot.

Thanks for the confirmation.

It’s somewhat strange when using Googles DNS that it is effectively blocking some of the sites blocked come under Google, Youtube and if using Firefox not Chrome. As an Avast User I draw the line at messing with my settings, sorry.
