Well.... yes.... it's busy scanning the whole filesystem like it's been
told to do.

If you're scanning a full system it's going to be busy for a while.
Even regular Windows desktop AV packages usually take at least 30-40
minutes for a full system scan.

They're not really "functions of the application", they're operational
requirements for it to do what you've asked it to do.
They're normal for any program that does a lot of heavy processing and
filesystem access. On *nix systems you can reduce its impact on other
processing by renicing (setting its priority) lower, and if you're using
a Windows build you should be able to use Task Manager to set the
priority low.
Very few programs I've seen will actively manage their actual CPU usage
so that they only use eg 50% of one core - some of the distributed
computing projects are the only ones I can think of offhand. Otherwise
most programs run flat-out while they're running.
