Urgent Notification - Trend Micro Pattern File 2.594.00 Causes High CPU
Utilization
______________________________________________________________
On April 22, 2005 at approximately 3:30 pm Pacific (11:30pm GMT) Trend
Micro posted 
a pattern file (2.594.00) which had the potential to interact with certain
computing 
configurations and cause computer performance issues for some users of
PC-cillin, 
OfficeScan (including the OfficeScan component of Client/Server Suite for
SMB
and Client/Server/Messaging Suite for SMB), and ServerProtect for NT. 

This specific pattern file was only available during an approximately
90-minute time 
window. Trend Micro removed the pattern file from our Web sites and Active
Update servers at 5:02pm 
(1:02am GMT), and immediately took steps to post a new pattern file.
Subsequent pattern files do not cause these issues.  

For any customers experiencing instability, Trend Micro has provided a set
of 
solutions which can be found under the Support section of Trend Micro?s Web
site at:

Additionally, Trend Micro has extended support hours especially to help
those customers who were affected by this issue. Further information,
instructions, and details can also be found on the Trend Micro Web site at:

We sincerely apologize for this incident and will continue to improve our
processes so that problems such as this do not happen in the future.
