Many thanks. Vsmon is one of the processes of the Zone Alarm Security Suite. By the way, I've used the ZA products for years and have migrated from their free firewall to ZA Pro to the full Suite, and found them very satisfactory. It eliminates nighmares that result from trying to run anti-virus from one vendor, firewall from another vendor, and anti-spyware from yet another. Yes, it takes a lot of resources, but at least it runs smoothly.
