Vital protection for your server data

High-performance mailbox server protection integrates perfectly with most popular operating systems, such as Windows Exchange 2003/2007/2010/2013 Server, via Microsoft’s Virus Scan APIs.

Built-in antispam

Antispam for Microsoft Exchange servers 2007/2010/2013 with the latest Service Pack keeps your mailbox free of SPAM and phishing scams.

Benefit from real-time protection

Your virus database will be continuously updated with the latest definitions in real-time via connection to the Avast Virus Lab, so your network will have even new ‘zero-day’ threat signatures as soon as we do.

Be in control with real-time alerts

Our easy-to-navigate graphical user interface (GUI) offers a user-friendly central window to all program functions. Comprehensive reporting options provide adjustable parameters for what information gets reported and how often.

Simple and convenient licensing

Licenses can be purchased on a per-server basis (rather than per mailbox), for greater convenience.

User interface (UI)

The Avast UI has been redesigned to keep up with modern navigation styles.

Antivirus and anti-spyware engine

Our award-winning scanning engine protects against viruses, spyware, and other malicious agents, now with a new algorithm that is based on machine learning, which can process new-virus data in milliseconds rather than hours.
