How to remove a 'scheduled scan'

Hey, I was wondering if someone could help me with removing this scan that is scheduled as it gives me no option to delete it.

If I can’t remove it how can I edit it so it takes less time and doesn’t affect anything I’m doing, as it takes ages and slows everything down

  • Which Avast…? (Free/Pro/IS/Premier)
  • Which version…?
  • OS…? (32/64 Bit…? - which SP/Build…?)
  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?

its avast premier
version: 19.3.2369 (build 19.3.4241.450)
not sure on OS
the only other thing I have is Avast Clean Up Premium
I have no idea what version I had before as I had it for so long

  1. Download Avast Premier Antivirus: https://files.avast.com/iavs9x/avast_premier_antivirus_setup_offline.exe
  2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions…!!)
  3. Reinstall Avast with the downloaded installer from point 1.
  4. Reboot.
