Those same list of entries will continue to be reported, a) if the reason given is legitimate for the particular location/program, b) if they relate to something like spybot S&D quarantine items (and you didn't remove old items from its quarantine ?).
Remember - Files that can't be scanned are just that, not an indication they are suspicious/infected, just unable to be scanned.
This is however, total speculation as you haven't given enough examples of the files, location and reason why the files can't be scanned. The biggest issue seems to be password protected and a number of applications do this to protect their files and quarantine, etc. and avast isn't privy to the password, so it won't be able to open them.
So if you can post some more of the common files/locations (outside of the AOHell and S&D examples you already gave) and reasons then we can try to identify if this is a legitimate reason why a file isn't being scanned.
I have zero experience of AOHell having avoided it for all my computer life, if you no longer use AOHell for your ISP or use any other AOHell services, e.g. its free email service, etc. Then you should investigate uninstalling it, how you would do this I can't even begin to advise.
Your scan is completing as the display of the list is the final part of the scan process, displaying the list of files that couldn't be scanned.
