Avast is running under services and tasks. However, it's not showing up in the 'Running Programs' area on my toolbar/desktop. It shows the 'unknown' icon and says avastui.exe is corrupted or unreadable. Tried to reinstall but it didn't fix anything. I have the Premier license. I want to be able to change the setting that shuts down the pc after scanning. Or allows me the option of a yes/no "do you want to shut down". It's frustrating to be in the middle of something and it just tells me "I'm shutting down now".
