AVG blocking Quora.com

Hello Linwood ,
Thank you for contacting AVG Community Support.
I apologize for the issue you're experiencing with Thunderbird and the blue screen after the AVG update.
To assist you better, could you please let me know the device and operating system you're using?
Additionally, a screenshot of the UI would be helpful for further assistance.

When my Thunderbird email continues a story to Quora.com my screen turns blue and locks there. This began a few days ago after an AVG update. How can this be stopped?

Thanks for your response. AVG was updated and apparently blocked Quora.com. I updated again and all is OK now. Again, thanks.
