Deb, The way I understand it is this: If and when you disable System Restore, and then restart the pc that purges the files that were in system restore out of the restore system. When you restart the system restore, the infected files in the restore system are forever gone. You can then turn on System restore which then will create a set of new restore dates. This sometimes is the only way to get rid of malware that has been in the restore system files. :slight_smile:
