Windows Defender Failed to Initialize

Thanks, Engel! This looked right, but doesn’t seem to apply to Vista.
Running appwiz.cpl, Windows Defender doesn't even show up on the list of
installed Program and Features, nor under Windows features to turn on or off.
It is also not listed in the Windows Installer CleanUp utility
(http://support.microsoft.com/kb/290301/). And when I try to reinstall from
http://www.microsoft.com/athome/secu...yware/software, as the KB article
instructs, I get the message “You do not need to install this software
because Windows Defender is included in Windows Vista. You can access
Windows Defender from the Security section of the Windows Control Panel.�

Windows Security Center shows (under “Malware protection�) that Windows
Defender is turned off. “Turn on now� churns for a while, then says,
“Security Center can’t turn on Windows Defender. Please try again later.�

Any other ideas?

Hi Nevet,

I'm not sure about this--but it looks promising--

Good luck

Hi Nevet. You might try this. Go to the main Windows Update window and
click on "Installed Updates" (on the left-hand side of the window, at the
bottom), and then remove "Update for Microsoft Windows (KB931099)" (only).
Reboot. Reboot again. Go back to Windows Update, and re-install the same
update, by clicking on the Check for Updates button.

This should essentially re-install Windows Defender on Vista.

You could try this.

Go to Control Panel (Classic View) > Windows Update. Click on Change
Settings. Choose "Never check for updates (not recommended)". Un-check the
box under "Recommended updates". Click on Okay. Close Windows Update.

Go to Control Panel (Classic View) > Windows Firewall. Click on Change
Settings. Choose "Off (not recommended)". (Apply, OK). Close Windows
Firewall.

Try starting Windows Defender (Start Menu\Programs). If it starts, click on
the down-arrow to the right of the Help icon, and choose "Check for
updates". Let Defender check and download the update.

If Defender does not open, or if it opens, but doesn't download the update,
go to http://www.microsoft.com/security/portal/

Under "Latest Definition Updates", choose your operating system type, 32-bit
or 64-bit, and try the manual download. Note here the instructions
pertinent to Vista: http://www.microsoft.com/security/portal/ADL.aspx#top

Hoping this works, but either way, re-enable Windows Firewall and put your
Windows Update settings back the way they were.
