Question CPU at 100% after installing new hard drive

So I decided to buy a new Western Digital 2tb Hard Drive. After I got done installing it I decided to install CS GO and Apex on it first.
When I started playing CS GO (Apex was still downloading) I noticed some stuttering and checked task manager and saw that my CPU was at 100%.
I restarted my computer and at idle it still goes to 100%
Why is that?
My CPU is a Ryzen 5 2600

It does the same thing
100% sometimes at idle without the hard drive
It's probably Chrome doing it's "harmful programs" and "malware" scan. It's the reason I tossed Chrome in favor of Brave, which is based on Chrome, but without most of the google garbage. Chrome would constantly scan and all I could hear was my storage drives sounding like banshees wailing for hours until I figured out it was Chrome scanning all my drives. I would uninstall Chrome and either install Firefox or try Brave if you prefer the Chrome UI. https://brave.com/

Is your hard drive brand new or used new?? I had a drive go bad and it was causing my CPU to run at 100% when I was copying files or running anything off it.

I've never had an issue with chrome, maybe I've just been lucky.
 
Your Kaspersky may have been configured for idle scan which is normal and with a new drive it will scan in the background. Bitdefender likewise will do an initial full scan on install (so this is overhead associated with installing a new HDD) - you can tinker with the scan settings to make it less intensive. either way it should resolve itself once the AV makes its first clean pass
