Avast blocking sites

Hello. After last update I have big problem. Avast is blocking facebook, sometimes gmail, youtube, and many other sites. What is happening? After disabling avast everything runs normaly. My version is 2014.9.0.2011.

It even blocks google search;/

Did you upgrade via the user interface? If yes:

I’d recommend a clean install of v9.0.2011.

  1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition

Avastclear : http://files.avast.com/iavs9x/avastclear.exe
Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/

  1. Uninstall Avast by control panel [If you don’t have Avast in control Panel go to #4]
  2. Uninstall in safe mode using Avastclear.
  3. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn’t) - reboot.
  4. Install the version you downloaded.
  5. Reboot.

Still not working. Now it can’t download updates of virus database. My devices tab don’t load. I can’t download files from websites;/

Guess i have to install different antivirus;/
