New Avast blocks youtube (flash plug-in?) and downloading files.

Avast Free Antivirus / Premium Security
1

Hi,
I’ve got a problem with watching youtube.com after updateting Avast (free version) to 2014.09. At the beginning I thought it was something with my browser, so I changed it (from Opera to Firefox). The thing is, that every film craches after few seconds. When I disable Avast everything goes normal. I have the newest version of adobe flash, the same is with Firefox, IE, Opera. I have already reduced sensitivity of protection - It didn’t help. Also, I have added youtube.com to the exceptions - the same story. Another thing is, that avast is causing problems woth downloading any files, mostly it stops at 99%. It’s really frustrating, please, help!
I’ve got Win 8, 64-bit.

Are you on 8 or 8.1 ? Upgrading to 8.1 will probably fix the problem.

8.1, unfortunately.

A fresh install may solve it. I would say give it a try.

  1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition.
    Here are the installer links. Note: You need to be ONLINE during this install.

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. Be Sure Too Check Once Uninstall is Complete:Device Manager>View>Show Hidden Devices
    If there is anything related to Avast with a yellow triangle then uninstall it (highlight, right click) and reboot.
  5. Install the version you downloaded.
  6. Reboot.
