Hi, my computer recently updated AVG, and since then I am unable to use Firefox as a browser when the Wed Shield is turned on (I get error messages about unknown certificates). It works fine when Web Shield is turned off. I've tried uninstalling and reinstalling AVG, but the same problem occurs when AVG does an update. Restarting the computer does nothing either. Could anyone advise me of a way to fix this? I see it's a problem a number of people have had.
Rachel,
Thank you for providing the screenshot and I appreciate your extended efforts so far. This issue is most likely caused because we are adding AVG certificate into the Firefox. 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.
Hello, Rachel.
I regret to hear about the inconvenience this may have caused to you. Please run the following command in the terminal: "/Library/Application Support/AVGAntivirus/hub/usermodules/020_cert.sh" start and restart the computer. Now verify your issue with AVG Web Shield enabled.
Thank you for letting us know, Rachel.
We're glad we were able to put you at ease. If you need anything else, do not hesitate to let us know.

Hi Avinash, thanks for your message. I have done as you suggested, but this unfortunately doesn't seem to have fixed the problem. Might you have any other suggestions? Thanks!
