SYMPTOMS

By default, Microsoft Anti-Virus and Microsoft Anti-Virus for Windows store a CHKLIST.MS file (marked with the Archive file attribute) in each directory they scan. If the CHKLIST.MS file has a Read-Only, System, or Hidden file attribute, certain Anti-Virus functions do not work.

CAUSE

When a file (such as CONFIG.SYS) changes, Anti-Virus detects the change and asks to update the file. If the file has a Read-Only, System, or Hidden attribute, Anti-Virus does not update the CHKLIST.MS file even if you choose to update it.

This problem also occurs on network drives when you do not have write privileges to a directory Anti-Virus is scanning.

If the CHKLIST.MS files have the Read-Only attribute set when you choose Delete CHKLIST Files, the files are not deleted; however, Microsoft Anti-Virus gives no indication that the files were not deleted. System and Hidden attributes have no effect on this process.

WORKAROUND

To work around this problem, remove any Read-Only, Hidden, or System file attributes from the CHKLIST.MS files. If you are scanning a network drive, you must have write privileges to all directories scanned by Anti-Virus.
