Hello everybody First of all I have to apologize on behalf of Trend Micro. I understand that you faced severe problems due to a significant performance issue on PC's that have loaded the pattern file 2.594.00
Manual Solution: To fix this problem, please follow the solution #24263 (Office Scan) and #24264 (PC-cillin Internet Security Suite) http://kb.trendmicro.com/solutions/search/main/search/solutionDetail.asp ?solutionId=24263 http://kb.trendmicro.com/solutions/search/main/search/solutionDetail.asp ?solutionId=24264 Explanation: On April 22, 2005, starting at 3:33 pm Pacific (10:33 GMT) Trend Micro posted a pattern file (2.594.00) that had the potential to interact with certain computing configurations and cause computer performance issues for some users. This specific pattern file was only available during a 1 hour and 29 minute time window. Trend Micro removed the pattern file from our Web sites and Active Update servers at 5:02 pm (1:02 GMT), and immediately took steps to post a new pattern file. Subsequent pattern file downloads do not cause these issues. Right now Trend Micro global support team is working to fully understand the extent of the problem and provide additional solutions. Trend Micro has extended support hours especially to help those customers who had this special intersection of circumstances and were affected by this issue. Trend Micro is continuing testing in order to fully understand initial assessments and fix the issue, and endeavor to provide additional information as it becomes available.

Once he started Trend Officescan service the System process spiked. Possible update today on Trend that botched it? > > Jonathan Grotegut http://kb.trendmicro.com/solutions/search/main/search/SolutionDetail.asp ?SolutionID=24263&btnSearch=GO "Windows XP Service Pack 2 machines with critical patches and OfficeScan Corporate Edition (OSCE) starts to experience high CPU utilization after updating to Pattern 594" 594 was released today, and then 596 was released immediately afterwards. It looks like the machines having problems on my network are running 594 and weren't able to successfully update to 596. Coincidence? I think not. Thanks Trend. You've ruined my Friday night. My girlfriend and I thank you... -- Benjamin Krueger "Nakedness is sinful.
