I use XP Pro SP2 with all updates. Had your same Defender problem for almost
1.5 month. On April 1, I purchased OneCare and that gave me access to a less
than 24 hours MS Support Engineer problem reply, all because Defender is part
of it. The solution given, was the complete removal of the old corrupted
Defender and its subsequent reinstallation.
The incorrect removal of Defender and reinstallation may cause a malfunction
in
the weekly Signature version updating. One fix for this problem is applying
the
KB article 915105 Resolution, on a weekly basis, before doing the Windows
Update. Another
fix is the complete Windows Defender program removal and reinstallation. The
latter will
not require to run the Resolution, for the Signature to update automatically
using Windows Update.
Follow all the steps carefully, it worked for me and can do the same for you.
Step 1:
============
Before removing a program it must be stop and exited.
Stop and close Defender as follows: Click the Tool tab / General Settings /
scroll down to Real time protection options and uncheck Turn on real-time
protection (recommended) / click Save and exit. If you are also using
Windows Live Onecare,
go to View and Change Settings and on the Antivirus tab select Off,
click Ok and exit. Then follow the next two Steps sent to me by Vanessa Hu, a
Microsoft Support Engineer.
Step 2:
============
1. Click Start, click Run, type "msiexec /x
{A5CC2A09-E9D3-49EC-923D-03874BBD4C2C}" (without quotation marks) in the Open
box, and then click OK.
2. Download and install the Windows Installer Cleanup utility from this
following link:

3. Run the utility from Start -> All Programs -> Windows Install Clean Up.
4. Select all Windows Defender related entries from the list (if there are)
and click Remove.
Step 3:
============
1. Open Internet Explorer.
2. Download and install Windows Defender from the following link and reboot
the computer:

3. Please go to Microsoft Update:
http://update.microsoft.com/microsoftupdate/ and install the updates for
Windows Defender.
Done all the above the Defender will updated and work to perfection.
