Of course not… Why would you restore infected files? Am I understanding you correctly? You are going to restore infected files (not the system ones) from avast Chest and then disable system restore? Why?
You can disable the system restore, all restoring points will be lost, clean your system.
Why do you need to restore the infected files from Chest?
I’m only asking to not give you the wrong answer…

No, it’s not the file on the Chest which is ‘coming back’, but the ones into System Restore folder :wink:
