Scenario
Scenario 1: This company wants to install an antivirus gateway appliance to scan all incoming e-mail and Web traffic for its 150 users. Approximate budget: Open.
Requires: One antivirus appliance.
Concerns: The company is concerned the appliance may affect throughput of Internet and mail traffic. The appliance should be easy to manage remotely. The frequency of virus definition updates is also a concern.
Best solution: If you already have a firewall in place then the obvious choice for your antivirus appliance is McAfee WebShield e250. Of the appliances tested the McAfee product is the most flexible and feature rich in terms of its AV prowess and is reasonably priced.
On the other hand, if you were also looking around for a firewall and intrusion detection appliance as well, which of course was not the thrust of this comparison, then the inexpensive FortiGate NPG 200 is hard to go past— although it’s not quite as feature rich as the Symantec appliance it is nevertheless around a fifth its price.

Once you know what modern worms do with emails (hint: they fake "from" field), thinking like "it would be helpful if the AVA sent a message back to the sender warning them that they passed on malicious code" is, in my opinion, step in spreading spam around the world.
