## Trend Micro Scan Technology

ScanMail allows administrators to choose the level of malware detection that is appropriate for the company’s security policy. Administrators configure the security level ScanMail provides by configuring the scan engine and any further analyses necessary.
The following table outlines the scanning technology available in ScanMail.

#### Scanning Technology

Scan Technology | Description
--- | ---
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) | Advanced Threat Scan Engine 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. Advanced Threat Scan Engine enhances the features provided by the Virus Scan Engine. For more information on Advanced Threat Scan Engine configuration, see Configuring Security Risk Scan Targets.
Virtual Analyzer | Virtual Analyzer 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 or URLs attached to messages contain exploit code. Although many files or URLs do not include executable data, attackers find ways to cause such files or URLs to exploit vulnerabilities in programs and operating systems that run them. Because of this, sending malicious files or URLs to target users has become an effective way for attackers to compromise systems.
| ##### Note Virtual Analyzer is a separately licensed product that provides unique security visibility based on Trend Micro's proprietary threat analysis and recommendation engines. ScanMail integrates with the Virtual Analyzer in Deep Discovery Advisor and Deep Discovery Analyzer.
For more information on Virtual Analyzer settings, see Configuring Virtual Analyzer.
