Windows Defender removal?



Please accept my apologise for placing the wrong group as I got hundred of
lists in the discussion group and could not find for spyware, Windows
Defender or Windows XP Installer in the list!! I am hoping if you could help?

Every time computer reboot, the error message given "Application failed to
initialize: 0x008106ba. A problem caused windows defender service to stop"

I attempted to remove Windows Defender via ARP, the error message given "The
Windows Installer Service could not be accessed, This can occur if you are
running Windows in safe mode, or if the windows installer is not correctly
installed. Contact your support personnel for assistance."

Also I tried to upgrade WD, and give error message... "Another version of
this product is already installed. Installation of this version cannot
continue. To configure or remove the existing version of this product using

I found some useful Microsoft knowledge base support and forum, such as
msiexec /unregister and /regserver etc. Nothing changed. I have done other
links are...

In Event Viewer states MsiInstaller, ID:1015, Failed to connect to server
Error 0x80070005. no information from help or MS support.

I could not find any solution to get rid of Windows Defender?
This system is Windows XP SP2, MSI v3.1

Please help?


Dave: Try this first with WD,

Hello Nel,

So--the way to dig into this:

Windows Defender records, in the System event log, at the time of the scan,
the precise path and filename of each detection.

So--right click My Computer, choose Manage.
Click on the plus sign in front of Event Viewer.
Click on the System events log, in the left column.
Click on View (top menu), filter.
Click the down-arrow at the right of Event Source, and choose "WinDefend."
Click apply, click OK.

Now--in the right window, scroll back to the time of the original detection,
and look for yellow-triangle marked records for those original detections.
Double-click a record in the right window to open it and see the full
detail. You can cut and paste, via a button--back to this thread.

Some possibilities are that the items detected are in the System Restore
storage area, an antivirus Quarantine, or, perhaps, is an archive file of
some sort, which might contain valid data in addition to the spyware

To delete all but the last System Restore point.

Open Disk Cleanup via Start, Programs, Accessories, System Tººls.
It will scan the system first. Click the More Options tªb.
Now click the Clean up button under System Restºre.
This will remove all but the most recent restore pºint.

For the benefit of the community reading this post, please rate the pºst.

I hope this post is helpful.

Let us know how it works ºut.

Excellent--that article should do the job, and I'd forgotten that it had the
additional content that makes it useful.
