Troubleshooting the error: "Windows Live OneCare Antivirus service could not start"
After you update Windows Live OneCare, you may receive the following red action items when the Antivirus service attempts to start:
Turn on Antivirus monitoring (At risk)
Windows Live OneCare Antivirus service could not start. (At risk)
This problem can occur if a third-party tune-up or user interface modification program has changed the startup screen that Microsoft Windows XP displays during the startup process. This changes the default kernel file that Windows XP uses to start and can prevent Windows Live OneCare Antivirus from starting.
Changes made to the kernel by third-party software can expose your computer to potential security risks. Because the new kernel isn’t a Windows XP kernel, Microsoft can't verify its security. Additionally, future Windows XP security updates for the original kernel won’t be applied to your computer.
To resolve this problem:
- Click the Windows Live OneCare icon in the notification area of your taskbar.
- Click Help, and then click About Windows Live OneCare. Verify that the version of Windows Live OneCare is 1.0.0960.8 or later.
- Click OK.
- Click View and Change Settings.
- Click the Logging tab, and then click Create support log.
- The support log document opens in your Web browser. In the Snapshot section of the support log, verify that the Action items entry has the following entries:
- Turn on Antivirus monitoring (At risk)
- Windows Live OneCare Antivirus service could not start. (At risk)
- Close your Web browser.
- Click Start, click Run, type Winver, and then click OK.
- Make note of the Windows XP version number.
