I suspect there was no detection or you would have been alerted and asked for an action and that these are in fact back-up copies in the System Files section of the chest.
I really do wish Alwil would get rid of this All Chest Files collation of the three sections:
The only area you should be interested in is the Infected Files section, this is where the files detected by avast and selected by you to move to the chest are placed.- The User Files section is where the user can add files they suspect of being malware but not detected by avast.- The System Files section is where avast keeps back-up copies of important system files in case the original becomes infected (leave them alone).- The All Chest Files is a collation of the three sections.
Yes it is wrong, as Recover/Restore tries to replace a windows system file that is in use and will be protected by windows. So I presume that you got an error message when you tried that ?
These files in the System Files section of the chest are for avast use. Not only that but the files in the original location aren’t infected or avast would have alerted.
