icons flashing and displaying “cleaning...” normal?

[Monsterariviera]

Have noticed my IOS icons flash dark in random order while the app icon text is temporarily changed to “cleaning...”. Is this part of malwarebytes? Never seen this behavior in iOS before.

That indicates that your iDevice is deleting temporary files. You Application Icon or icons on your Home Screen may dim briefly (looks like you tap them) then comes back to normal. If the deleting process takes long, there will also be a message under that application icon saying "cleaning..." If the cleaning process is short, the icon dims/blinks for a second and goes back to normal once the files are deleted.
