Cupertino, California – December 10, 2007 – Trend Micro Incorporated (TSE: 4704), a leader in network antivirus and content security software and services, today announced that Trend Micro Mobile Security (TMMS) 3.0 is available for the Symbian/UIQ 3.0 operating system, which includes Sony Ericsson P1 devices. New users can directly download a trial version of TMMS 3.0, protecting them from hackers, intrusions and malicious codes that are an ever-increasing threat to mobile devices using unsecured wireless networks. The solution also protects against data leaks through firewall and intrusion detection technologies.

Mobile devices are rapidly outnumbering PCs, becoming faster, more powerful and convenient for a mobile workforce that needs access to company-specific information through various wireless networks such as Wi-Fi. Trend Micro Mobile Security 3.0 offers mobile devices the same type of protection needed for PCs -- antivirus, firewalls and anti-spyware. At the same time, it protects business-critical data stored on these devices if they are lost or stolen.

"We are delighted that Sony Ericsson P1 users now have the option to protect themselves with Trend Micro Mobile Security 3.0,” said Per Alksten, senior application manager at Sony Ericsson. “We hope this added convenience will encourage our customers to equip themselves with a comprehensive and effective mobile security solution.”

“Trend Micro strives to be one step ahead of the bad guys,” said Todd Thiemann, marketing director for Trend Micro's incubation group. “Smartphone usage and convenience are expanding quickly. Even though the mobile threats we've encountered so far have been containable, our goal is to 'future-proof' our customers with the best security solutions we can deliver.”

Trend Micro Mobile Security 3.0 is designed for maximum ease-of-use, providing users with a simple interface for maximum security with minimal impact on the user and device. Trend Micro Mobile Security 3.0 supports devices using Symbian OS 9.1/UIQ 3.0 which includes the Sony Ericsson P1, W960 and M600. Trend Micro Mobile Security 3.0 for Windows Mobile™ 5.0/6.0 has been available since late November 2006 while Trend Micro Mobile Security 3.0 for Symbian/S60 3rd Edition has been shipping since April 2007.
