Windows Defender Service Error

    Question

  • Just yesterday, the Windows Defender service stopped starting. Upon starting the comp, I get the 0x800106ba error, telling me that a problem has caused the service to stop. This happens whenever I try to run MCASCui.exe as well. When I try to start the service manually, it gives me error 1053, telling me that the service did not respond to the start or control request.

    My computer was infected with a virus, and since Windows Defender no longer works, I have about 15 trojans on the computer now. Many of which I have manually deleted. Since Windows Defender service doesn't start, I'm pretty much screwed, since these trojans keep downloading other trojans.

    I am running Windows XP Home edition, and the version of Windows Defender is not the Beta version. It is the latest version. However, I have tried uninstalling the program and then re-installing it, but during the installation, it won't finish the install because it cannot start the service to complete the installation.

    If anyone can give me a straight solution to this, I would be extremely pleased. I've spent the past 24 hours searching every website on google, but nothing helps.
