Update - Restart Issues After Installing MS10-015 and the Alureon Rootkit

[anyweb]

We wanted to provide you with an update on our ongoing investigation into the “blue screen” issues affecting a limited number of customers who installed MS10-015. We have been working around the clock with our customers, partners and several teams at Microsoft to determine the cause of these issues. Our investigation has concluded that the reboot occurs because the system is infected with malware, specifically the Alureon rootkit. We were able to reach this conclusion after the comprehensive analysis of memory dumps obtained from multiple customer machines and extensive testing against third party applications and software. The restarts are the result of modifications the Alureon rootkit makes to Windows Kernel binaries, which places these systems in an unstable state. In every investigated incident, we have not found quality issues with security update MS10-015. Our guidance remains the same: customers should continue to deploy this month’s security updates and make sure their systems are up-to-date with the latest anti-virus software.

 

Customers continue to emphasize the importance of quality updates, and that high quality updates encourages quicker deployment. While the issue customers are experiencing with MS10-015 was caused by a malware infection and not a problem with the security update, we wanted to use this event as an opportunity to explain why this issue was not caught during testing, and how we respond to reported issues in our security updates.
