Windows Defender quit working

I purchased a new Dell computer with Windows Vista and IE7. When I went to
upgrade to IE8, download and install was successful. At least I thought it
was until I rebooted and recieved the message that Defender was no longer
running. And I am unable to get it running.

Please advise.

Please state your full Windows version (e.g., Vista SP1; Vista x64 SP2) when
posting to this newsgroup.

Is a McAfee application installed or had a McAfee application ever been
installed?

Please post the complete (verbatim) error message.

In the Processes tab of Task Manager, are the following processes
listed?

MSASCui.exe
MsMpEng.exe

If they aren't listed, do they show up when you use the Start menu
shortcut to load [the UI for] Windows Defender?

When you go into the Services applet (services.msc), is the Windows
Defender service listed for Automatic startup mode? If it is shown as
Disabled then it will never start. If it is shown as currently Stopped
(and either Automatic or Manual startup mode), what happens when you
manually Start it?

What other security products are installed on your host (anti-virus,
anti-malware, anti-spam, HIPS, firewall, etc)?

Is Windows Defender to which you refer the separate security product by
that name or is it a component of the new (but limited beta) Microsoft
Security Essentials product?

Have you tried downloading the .msi installation file, uninstalled
Windows Defender, and then reinstalled it?

Windows Vista Home Premium
SP1


ERROR
Application failed to initialize: 0x800106ba. A problem caused this
program's service to stop. To start the service, restart you computer or
search Help and Support for how to start a service manually.

McAfee is installed but I have disabled everything.

I just did a windows download that was pushed to me from Microsoft and now I
was able to start Defender.
