Web Shield blocks Firefox

Hi,
I'm on a Mac. When I enable the Web Shield with this new version of AVG AntiVirus, Firefox doesn't work and give me the "SEC_ERROR_UNKNOWN_ISSUER" error. When I disable the web shield, Firefox works.
Google Chrome is working when the web shield is on.
Thanks.

Hello, Rom.

I regret to hear about the inconvenience this may have caused to you. This issue is most likely caused because we are adding AVG certificate into the Firefox. Please follow the steps below to resolve the issue.

1. Close the Firefox app completely.
2. Run the following command in the terminal: "/Library/Application Support/AVGAntivirus/hub/usermodules/020_ cert.sh " start
3. Restart the computer.

Now verify your issue with AVG Web Shield enabled.

If the issue persist, we would request you to try and add the AVG certificate to Firefox manually to resolve the issue.

To start with, it is necessary to obtain a copy of the certificate.
This can be found with Keychain Access with Keychain "login" and category "Certificates". Search for "avg". You should find "AVG trusted CA". Select it and export it from the menu bar under "File" then "Export Items...". Save it somewhere accessible.

Now, the certificate needs to be added to Firefox's certificate manager.
Open Firefox's Preferences > Privacy & Security tab. Scroll down to Security > Certificates. Open "View Certificates...". Click on "Authorities" then "Import...". Import "AVG trusted CA" and trust it to "identify websites". You can select "identify mail users" if you want.

Thank you for confirming that the second step fixes the issue. We will update the same for other customers.

Well, I am a not so ahppy customer. I tried the 2nd option with no fix since my version of AVG is rejecting the certificate

Hi Andrdeas,

We apologize for the inconvenience caused.

We request you to uninstall the AVG Antivirus program from your Mac, and reinstall the program then try to access Firefox and see if you could access it.

If not, please provide us the Mac version and the version of the AVG program installed on your PC. Also share us the screenshot of the error message to check and assist you further.

Thanks,
Vishnu Vardan

Alright, have you tried to uninstalling and reinstalling the AVG Antivirus program to check with the issue?

If not please uninstall and reinstall the AVG Antivirus application and check if you could access Firefox on your Mac device.
