Avast Internet Security not starting

Avast Free Antivirus / Premium Security
1

Hello,

I installed a disk image a few months old, containing the version before last. Avast asked me to update the program. I did, but afterwards it did not start with “failed to load language.dll (2057)” problem. Then I repaired it through Windows Programs and Features. Now it still does not start and gives the following error window:

The exception unknown software exception (ox06d007f) occurred in the application at location 0x777bc41f.

What can I do to make it work, please? I read in the forum that people uninstalled with Avast uninstallaer, but the language.dll error remained.

Edit: This last message keeps coming back every time I click on OK to make it go; so it stays permanently on the screen.

Do you have any other security related applications?

If you have Windows Firewall/Defender enabled make sure to disable them.

This should fix it:

You stated you tried a clean install but there’s some additional stuff here.

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

Note: It’s important you used the stub online installer from the one I linked… NOT the offline one.

Note: You need to be ONLINE during this install (online installer works in all cases whereas offline sometimes doesn’t)

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.
    Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle… if so, uninstall it and reboot.
  4. Install the version you downloaded.
  5. Reboot.

Note : If you have a paid license, install it after the reboot at stage 6.

Hi, Alikhan, Thank you for your reply.

Some of your instructions I had already done, than I followed the other ones, but no way, it never started. Then I searched through directories and files and found there was another directory named Avast with the same usually installed files, as a second installation. I cleaned them up with Avastcleaner to also delete their corresponding registry keys, as I thought it would do. After this I reinstalled, updated and it was fine as before. What a headache!

Thank you for your help and good will.
