We already have [insert name of AV product]. Can we use it with LISTSERV instead of Windows Defender?

Yes, to a limited extent, under Windows (LISTSERV Classic or Classic HPO) only. Please see the LISTSERV manuals for information on the FOREIGN_ANTI_VIRUS site configuration parameter and its use.

The FOREIGN_ANTI_VIRUS feature is available only for Windows, and does not work with the Anti-Virus Station (AVS).

The FOREIGN_ANTI_VIRUS feature is not available for LISTSERV Lite.
