interscan viruswall
InterScan VirusWall provides high-performance, three-in-one Internet gateway protection against viruses and malicious code. The optional eManager adds spam blocking, content filtering, and email scheduling

Automatic Virus Pattern File Updates
Weekly updates of the virus pattern file are available from Trend Micro's Web site and can be automatically downloaded and installed. Emergency pattern files are made available on an 'as needed' basis.

Flexible Configuration and Internet-Enabled Management
InterScan VirusWall can be configured to respond to virus detection and security violation incidents in several ways, alone or in combination.

Easy-to-Manage, Robust Activity Log
InterScan VirusWall maintains a comprehensive activity log, which details for each infected file or attempted security violation: the origin, name and destination of the file, the date the file was received, the identity of the virus found, and the action taken. This allows administrators to easily track the source of problems and deal with them appropriately.

Trend's Proprietary Scan Engine
InterScan VirusWall uses Trend's multi-threaded, 32-bit scan engine to detect thousands of viruses, including 100% of those found on Joe Well's 'Wild List.' InterScan detects known and unknown viruses and recognizes more than 16 types of compression encoding formats and scans down as many as 20 layers of compression.
