Hard drive pinned at 100% usage

[albin9000]

I've been using Avast for as long as I can remember without any major issues but recently I've been noticing Avast using 100% of my HDD for about 30 minutes straight after logging in to the computer.
I've noticed that Avast have been doing background scans that I can't stop nor disable with the right click menu, is there a way of disabling background scans or at the very least change it so it doesn't use 100% of my disk access time? Because I don't like having to wait 30 minutes after logging into my computer to be able to use it instead of the usual 3-5 minutes

- Which Avast..? (Free/Premium)
- Which version/build of Avast..?
- OS..? (32/64 Bit..? - which SP/Build..?)
- Other security related software installed..?
- Which AV(s) did you use before Avast..?

Free version 20.10.2442 (version 20.10.5824.626)
Windows 7 Home Premium SP1 (64bit)
I have malwarebytes on my drive but I haven't ran it in a few months
I have not used any other AVs before Avast

1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup_offline.exe
2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions..!!)
3. Reinstall Avast with the downloaded installer from point 1.
4. Reboot.

According to Win10Pro 64b Task Manager, my HD Use has been pegged at around 100% by Avast Service>Antivirus 95% for most of several weeks, at the same time using variably 20 to 70% for CPU & Memory.
.  This makes doing anything else very difficult, not to mention wearing out my hardware with grossly unneeded work load!
.  Avast Premium TS # is busy, and the Forum has some complaints about this issue, but no usable answers, explanations, nor suggestions. 
. 21.6.2474 (build 21.6.6446.683), UI: 1.0.660
