Kaspersky Anti-Virus 6.0 for Windows Workstations (all builds)
All messages with the modification date prior to the date set in the archiving options are archived. The Anti-Spam component modifies the MAPI messages when scanning (flagging them as 'scanned') and the date of the message changes. Thus the date of the messages scanned by Anti-Spam may not coincide with the date restrictions set in the option.
