Most likely a corrupt install…
I’d recommend a clean install to v9.0.2013
- 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)

Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/
- Uninstall Avast by control panel [If you don’t have Avast in control Panel go to #4]
- Uninstall in safe mode using Avastclear.
- 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.
- Install the version you downloaded.
- Reboot.
