avast cleanup - takes too long to clean up

I just bought the avast clean up yesterday & try to clean up my laptop. It seems to take too long to process. Any idea is this normal or the software is not functioning?

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