How to prevent Avast Cleanup from loading on startup?

คาสิโนHi;my name is lala.
Whenever I turn on/restart my PC, the Avast Cleanup icon appears on the tray.

I tried disabling it using Task Manager => Startup, but it still appears every time my OS (Windows 10) starts up. Thank you for your advice.dreamgame
