Improved filter function in ScanMail for Exchange 3.7 recognises camouflaged email attachements

Marlow, England, 31 October 2001 - Trend Micro (Nasdaq: TMIC, TSE: 4704), a worldwide leader in network antivirus and Internet content security solutions is pleased to announce the forthcoming launch of a new version of ScanMail for Microsoft Exchange 5.5, Version 3.7. This latest release offers file type analysis and improved overall performance. ScanMail for Microsoft Exchange V.3.7 will be available in Q4 2001 from Trend Micro's Web site -

The most outstanding feature of Trend Micro's ScanMail for Microsoft Exchange V.3.7 is its improved filter function for file extensions. The program no longer blocks files on the basis of their file extensions, but instead identifies the real file type involved. Using this file type analysis feature, the program recognises an item like a camouflaged e-mail attachment with a .txt extension in which an infected .exe file is actually concealed. The file can then be blocked, preventing it from slipping through the filter and causing havoc throughout the network.

As in the previous version, ScanMail for Microsoft Exchange V.3.7 offers ESE API mode (Extensible Storage Engine Application Program Interface). This mode not only locates known viruses, but also renders potentially harmful file attachments safe before they can enter the network through the Exchange Server. The product provides all the usual ScanMail features, such as real-time scanning and scanning of outgoing e-mails, including complete scanning of attachments.

"In the past it was relatively easy for virus authors to rename documents or programs in such a way that they were invisible to the virus scanner. With the new file type analysis we are addressing the problem at the source," said Raimund Genes, European Vice President Sales and Marketing at Trend Micro.

ScanMail for Microsoft Exchange V.3.7 will be available as a download from Trend Micro's Web site: in Q4 2001. For more information please call +44 (0)1628 400500
