Hi JP
That driver updater on Avast, is to be honest, not the best advice to take when it comes to drivers, they make good security software, but that driver updater, like all driver updaters are not needed with Windows 10
Windows 10 updates will keep your drivers up to date, and as you point out the Intel software reported your Intel IME did not need to be updated . . .
Go to the support page for your PC on the manufacturers website, then on that page, check if they provide an updated version of Intel IME and if not, there is no update required on your PC . . .
