During VSA installation process (for example during patch installation), the add-on module list shows Antivirus/Antimalware module "version installed" as 184.108.40.206, even though the installed version of VSA and other modules is 9.1.
This is a cosmetic defect introduced in a recent patch release.
Installation of patch 220.127.116.11 will resolve the issue. After that, the module will be correctly reported as having version 18.104.22.168.
