Dr.Web for Microsoft Exchange Server is an anti-virus plug-in designed to protect corporate mail systems against viruses and spam. It flexibly integrates into the system and processes each message and attachment dispatched to the server. The scanning is carried out in memory buffers but not directly for the file system objects, that speeds up the process.
The important feature is that all incoming messages are processed in an order based on the scanning priority assigned to them. When a new message is located in the Microsoft Exchange Server Information Store, it is treated as a low priority object. As soon as a client attempts to access such message, the latter is reassigned to a high priority list and is processed in the first place. To ensure ultimate protection, outbound messages are processed prior to being passed to the client. Thus, changing of the messages priority provides perfect protection and efficient use of system resources.
Dr.Web for Microsoft Exchange Server also checks objects that are already located in the Microsoft Exchange Server Information Store, which considerably increases the scanning efficiency. Besides, to facilitate working with the plug-in, it is launched fully automatically (at system startup) and uses convenient update procedures (once added to the Windows Task Scheduler).
Dr.Web for Microsoft Exchange Server can perform the following functions:
| • | Scan all incoming and outgoing messages in real-time mode |
| • | Filter and block spam, use manually compiled black and white lists of addresses |
| • | Isolate infected and suspicious objects to Quarantine |
| • | Filter e-mail messages according to various criteria |
| • | Add accompanying text to outgoing external messages |
| • | Group clients to simplify their management |
| • | Send notifications on virus events and log them |
| • | Distribute reports on the operation of the plug-in |
| • | Automatically update virus databases and components of the plug-in |
Dr.Web for Microsoft Exchange Server uses virus databases which are constantly supplemented with new records to assure up-to-date protection. Also, a heuristic analyzer is used for additional protection against unknown viruses.
