Not sure what it is that you are seeing, a screenshot might help.
There is a new Title in the Smart Scan 'Advanced Issues' if that is what you mean ?
This I feel is no more than a vehicle to promote other Avast products, and is just one of the reasons I don't run the NOT so Smart Scan (outside of forum questions).
Thank you - here are my screen shots. I only use Avast Smart Scan occasionally, I find SuperAntiSpyware a much better option.
I don't want the Avast VPN thrust up my nose, I have my own
Scan settings - CLEANUP unchecked

Scan with the damned ADVANCED ISSUES showing

Unwanted RESULT - if I resolved these I would scuttle my own ship.

This is where I was confused the use of the term "Performance Scan" when I couldn't see this anywhere.
And the Advanced issues being a very much a catch all term that could mean anything. As I mentioned, I feel is no more than a vehicle to promote other Avast products.
In all honesty I would abandon any on-demand scan including the NOT so damn Smart Scan.
You can run the Outdated Apps scan (Software Updater in the UI Performance section. And the WiFi Inspector Scan, these I would say are worth at least running now and again, but the Outdated Apps should notify about those outdated apps that it covers.
As far as Cleanup goes, not having it installed is in fact the norm for Avast Free as it is a paid product, but avast are still going to try and push it. If you don't run the NOT so Smart Scan this really isn't an issue.
