Virus Scan Engine

The standard malware scan engine available in ScanMail.

The Virus Scan Engine employs pattern matching and heuristic scanning technology to identify threats before malware can infect a system.

Advanced Threat Scan Engine (ATSE)

ATSE performs aggressive heuristic scanning to check files for less conventional threats, including document exploits. Some detected files may be safe and should be further observed and analyzed in a virtual environment.

ATSE enhances the features provided by the Virus Scan Engine.

For more information on ATSE configuration, see Configuring Security Risk Scan Targets.

Deep Discovery Advisor

Deep Discovery Advisor provides a Virtual Analyzer that performs content simulation and analysis in an isolated virtual environment to identify characteristics commonly associated with many types of malware. In particular, Virtual Analyzer checks if files attached to messages contain exploit code. Although many files do not include executable data, attackers find ways to cause such files to exploit vulnerabilities in programs and operating systems that run them. Because of this, sending malicious files to target users has become an effective way for attackers to compromise systems.
