Etrust Antivirus Version 7.0

Installed it on a few systems, but don't want to start selling it without researching it first. We have it installed here at the shop on 2 systems, but I can't find much information about it. I'm trying to find out if it scans incoming and outgoing pop3 e-mails. One of my coworkers installed it on about 20 systems on a network, and I don't need a call one day (probably on a Monday) that they have 20 infected systems. If anyone out there has any experience with this I would greatly appreciate any feedback. Thank you and have a great day.
