              Trend Micro Announces Record Third Quarter Results

         Sales climb 42% YoY and ordinary income rises 22% in 3Q 2001

Tokyo, Japan - October 25, 2001 - Trend Micro Inc. (TSE: 4704; Nasdaq: TMIC), a
worldwide leader in antivirus and Internet content security solutions, reported
consolidated sales of 7,548 million yen (63 million US $) and ordinary income of
2,305 million yen (19 million US $) for the third quarter of fiscal 2001, ended
September 30, 2001. The figures reflect gains of 41.6% in sales and 22.1% in
ordinary income compared with the same period a year ago. This increase was
driven by solid, well-balanced growth in all three major markets: Japan, North
America, and Europe. Europe led all regions with rapid sales growth of 85% over
3Q 2000. Japan remained the largest market, with sales rising 32% to 2,921
million yen from 2,217 million yen in 2000 Major account wins in Q3 included
IBM, Sprint, Sony HSBC, US Deptt of Justice and Transportation, and City of
San Francisco.

If the results were not adjusted in accordance with a new revenue recognition
policy, sales would have shown annual growth of 49.6% to 7,973 million yen (66US
$), and ordinary income would have risen 44.6% to 2,730 million yen (22million
US $) in the quarter.

Financial data for the third quarter of FY 2000 is provided solely for
comparison purposes, as the Company did not prepare quarterly earnings
statements last year. Moreover, the figures for Q1 FY 2001 and Q1 FY 2000 have
not been audited by the Company's certified public accountants or independent
auditors, and the financial results described in this release were prepared in
accordance with Japanese generally accepted accounting principles (GAAP).

Note on Change in Accounting Principle
--------------------------------------
Until the end of FY 2000, the Company and Trend Micro Incorporated (Taiwan)
booked revenue for Premium Support and other post-contract customer support
services at the beginning of the support period.  Effective from FY 2001, the
method of recognizing this revenue recognition has been changed and sales
revenues from customer support are deferred over the relevant support period.

     The table below shows the year-on-year growth after restating the 2001
third quarter numbers to the revenue recognition policy in use during the
corresponding quarter of Fiscal 2000.

[Supplementary information about the consolidated results of third quarter of FY
2001]

     Basically, the product license agreement, which the parent company and its
subsidiaries contract with the end-user, states the article for Post-contract
Customer Support (customer support and upgrading of products and its pattern
files).

     Until previous consolidated fiscal year, total revenues of the parent
company and Trend Micro Incorporated (Taiwan) included a portion of Post-
contract Customer Support revenue, recognized at the time when the license was
delivered to user.

     Effective current consolidated fiscal year, the revenue recognition method
for portion of Post-contract Customer Support has changed as follows: Portion of
Post-contract Customer Support revenue is recognized separately from total
revenue and it is deferred as Deferred revenues under Current liabilities and
Non-current liabilities based on contracted period. Deferred revenue is finally
recognized for the contracted period evenly.

   The table below shows the year-on-year growth after restating the 2001 third
quarter numbers to the revenue recognition policy in use during the
corresponding quarter of Fiscal 2000.
