I have some files in the “Chest” that I want to know if they can be deleted or not.
D:\Program Files\Alwil Software\Avast4\Data\chest\00000004
D:\Program Files\Alwil Software\Avast4\Data\chest\00000001
D:\Program Files\Alwil Software\Avast4\Data\chest\00000002
D:\Program Files\Alwil Software\Avast4\Data\chest\00000003
As you might see there, these files are not in the Infected Items category but in the System files category = actually they are the backups of system files often modified by worms. It has been already discussed here…
