LISTSERV checks only the time stamp of the database files. It does not check  the last time it was checked by the F-Secure Auto-Update Agent. In rare cases, F-Secure may not have a virus signature update for 5 days or longer, so when the database file is determined to be five days old, LISTSERV begins notifying the non-quiet postmaster(s) to alert them to a possible problem.


In this case you should do the following:


Windows:  Check F-Secure's Automatic Update Agent to make sure that it is running. If it is, and if "fsav /version" reports that the signatures are up to date, then the warning can be ignored.


Linux:  Check to make sure that the F-Secure Automatic Update Agent (fsaua) is running.  This can be done with `service fsaua status` under Red Hat-like distributions.  If it is, and if "fsav --version" reports that the signatures are up to date, then the warning can be ignored.
