I’m curious whether Avast Free actually DOES ANYTHING? Seems to me like every notification about an issue then takes you to a page trying to suck some money out of you, force you to buy some other product to address the issue that the software apparently has found, seems like a scam to me.
The short answer is, Yes it does, you only have to check this forum to see. If you have a paid version of avast, you have more control over that.
The Free version will promote other Avast paid products, the cost of free 
I have been avast free antivirus for over 18 years, I gust smile and have an inward chuckle at some of them.
I don’t run on-demand scans or the smart scan, in an on-access antivirus this is much depreciated and these are likely to show promotions for paid products.
