Viruses spread too often through email attachments and can cause irreversible damage to your desktops. The necessity for enterprises to open up to the world makes them more than ever vulnerable to such attacks. Employees work more and more from home or from laptops, contributing to the increase of vulnerabilities, since the security on their pc is often not maintained on regular basis.

Implementing the antivirus directly on the email server will better protect your enterprise network against such threats as worms, a widespread type of virus that uses the infected user's address book to spread.
