Dears,

Message: I am having a problem to update my Windows Defender. When I try to
do it, I receive a message in the ballon :

Windows Defender was unable to complete the update: 0x80070005. Access is
denied.

Could you help me, pls?

Thanks in advance,
Claudio,
 
Hello Claudio,

Have you tried going to Windows Update and checking for available updates?
Can you go to Windows Update, do an Express (Get high-priority updates)
scan, and apply all offered updªtes
http://update.microsoft.com

Once that is finished, can you verify the update installs? There are many
pre-requisite files which are needed from windows update and signature update
with windows defender will fail until you hªve these files.

Just out of interest. Is this a Pc tablet?

Could you supply some information on what your OS is, firewall, anti-virus,
other RTP programs, browser, etc?

Are you on a large, managed network, where access to AutoUpdate is
restricted? Is there a WSUS server on the network?

What build of Windows Defender v. are you on--see the top version number in
Help, about... Engine v. Definition v.

Hi Engel..

I 've tried in four machines with differents softwares installed.

The common software is Mcafee ViruScan Enterprise 8.00.. with FW and without
it, I have the same problem...

In my personal machine, I have all available patches installed ( Windows XP
Professional SP2 )..and I 've the same problem..

It is not a PC Tablet..

Antivirus - Mcafee VirusScan Entreprise 8.00
FW - Zone Alarm Professional..
IExplorer..last version

Thanks for your help!!!!
 
Hi Claudio,

I'd recommend re-downloading, and saving to a known location--like the
desktop.
After the download is complete, disable real-time protection by your
antivirus for long enough to do the installation. Also disable any RTP
programs in the system tray

I hope this post is helpful, let us know how it works ºut.
