Adobe started to add “pasword” protection to some files.
Avast can’t open a file that has a password, simply because avast doesn’t know the password to use. So avast simply tells you that the particular file can’t be scanned deeper than it was already scanned.
It’s only information (which usually other AV tools don’t even bother to tell you about). It is not saying that you have some problem. It is what it is: the file is password protected.
In addition, in this case they are part of some restore point, but that’s another thing, and not an issue.
This is happening since not so long ago, since adobe started to add some protection to their files.
Getting rid of older system restore points (the real files, not just the list) would be a way to get rid of the log, but it is not going to have any real impact. You are safe.
