Inactive App - Antimalware Service Executable

I’m a bit concerned that Antimalware Service Executable has been inactive for a while now - my understanding is that this is connected to Windows defender, shouldn’t this always be running?

Thanks

Yes I have and it isn’t. It’s actually listed twice and both are inactive!?

Thanks @Geri123; it’s running withing task manager 177.6 MB constantly used in memory and very little CPU (0.1) usage
