Avast block facebook from opening

Thank you for the additional info, we are currently investigating this issue. If possible, can you please send us log files from your device? These logs would help with the investigation. The steps are quite complicated, so we respect if you don’t wish to spend time on this process.

A) Generate logs:

  1. Disable the Avast Self-Defense module in - Avast - Menu - Settings - Troubleshooting - uncheck “Enable Self-Defense”.
  2. In the same menu, scroll down to the bottom and check the option “Enable debug logging“.
  3. Download and import the registry file which is attached to this message - double-click it and confirm import of the required keys (they allows debug logs to exceed the default 8 MB file size).
  4. Ensure that the “QUIC-HTTP3-Scanning” is enabled in Web Guard settings.
  5. Restart your computer and wait till Avast is fully loaded.
  6. Open your web browser and attempt to visit Facebook.com - reproduce the loading screen (wait for around 2 minutes, if possible).

B) Submit logs:

  1. Follow the Support File submission process here: http://support.avast.com/en-ww/article/submit-support-file/
  2. In the field “Ticket number”, you can use the ID of this thread: 901431
  3. Finish the support file creation (no need to attach any file).
  4. Once the support file is created, please share its “File ID” in your response to this message.

C) Clean up:

  1. (Delete the log file “StreamFilter.log“ - it could grow to a couple of hundreds of MB. You can find it in this directory: C:\ProgramData\Avast Software\Avast\log)
  2. Enable the Avast Self-Defense module in - Menu - Settings - Troubleshooting - check “Enable Self-Defense”.
  3. In the same menu, scroll down to the bottom and uncheck the option “Enable debug logging“.

Let me know if you have questions.
