SYMPTOMS
After you update Microsoft Windows Live OneCare on a Microsoft Windows XP-based computer, the Antivirus service tries to start. In this case, you may receive the following error message:

Urgent

Turn on Antivirus monitoring. (At risk)

Windows Live OneCare Antivirus service could not start. (At risk)



CAUSE
This problem may be caused by a third-party program that performs user interface modification or a system tune-up. The problem may occur if this third-party program has changed the startup screen that Microsoft Windows XP displays during the startup process. To do this, the program may have changed the default kernel file that Windows XP uses to start. This change can affect Windows Live OneCare Antivirus and prevent the Windows Live OneCare Antivirus service from starting.

Warning Changes that are made to the Windows kernel by third-party software can expose a computer to potential security risks. After these changes are made, the kernel that is used is not a Windows kernel and has not been verified to be secure. Also, when third-party software changes the kernel in this manner, all future security updates to the kernel that are downloaded and installed by Windows are not applied to the computer. Therefore, the computer may be exposed to security risks.

To resolve this problem, you must contact Windows Live OneCare Technical Support. For more information about how to contact Windows Live OneCare Technical Support, visit the following Microsoft Web site:
