10 performance issues broken registry items

Avast has advised me that I have 6.7GB of system junk, 441 Broken Registry Items, and 10 programs slowing down my old Acer running up-to-date Windows 10. There is one button to click… “RESOLVE”.
I am loathed to click it. What if things are worse by doing that. It’s running okay - dont fix something that aint broke, is a motto that has saved me a lot of grief that I’ve witnessed firsthand.
Theres no explanation of anything about clicking “RESOLVE”, no assurances of any kind, and theres no facility to ask Avast directly. So why would I click it?
The only problem that I’m having is that whn I’m on Microsoft Google, sometimes, I get a feeeze up, mouse locks, fan goes into super fast speed, but NO ONE has been able to help me with that problem. I just crash shutdown, start again and its all fine til next time.

Resolve will show you results and if you have the paid version you can even
allow Avast to fix all of some of those items. ;D
