I receive the following error message when I try to scan any drive of my
computer using the Custom Scan. Beta 2 did not do this. Quick Scan and Full
Scan appear to work fine. Any suggestions?

Windows Defender scan has encountered an error and terminated.
Scan ID: {433154A0-20E7-42B2-9676-4F0A83E28729}

Hello Aaron,

Just out of interest. Are you using Spybot S&D with the Tea Timer active? Or
any other scanner as a Resident active.
 
No I do not. I do have Avira AntiVir installed, but I disabled the Guard
feature and still encountered this error. Other items of interest, I have 3
partitions:

1) System
2) Program Files
3) Documents and Settings

Only the first partition is assigned a drive letter (C:), the rest are
mounted via NTFS junctions under the C: drive in the corresponding folders to
allow for transparent partitioning of those files. I noticed in this final
release that these NTFS junction folders no longer show up in the selection
list, whereas they did in beta 2, so something changed. I don't know if it's
related or not, but I figured it was worth mentioning that's broken too.
 
There is two possibilities:

1. You selected a drive that is not connected to your computer (i.e.
removabnle media or wrong address ex: N:/)

2. You may have a corrupt partition.

So, I reccomend checking which drives Defender is checking, and making sure
your computer is normal (Watch for any signs of break down or strangeness
like sudden slowdown). Let me know what happens.
 
Thanks for the suggestions.

1. This happens when I select drive C. I am not selecting a removable disk.

2. Chkdsk reports everything is fine.

I am not experiencing any unusual behavior with my other software.
 
Hmm... Try the golden fixer if all does not work:

Reinstall the program.

Of course, if you need it then don't.
PS: You can enable AntiVir Antivirus Guard. It's not the problem.
 
I have reinstalled Windows Defender, but the release version still does not
work. I really believe this has something to do with NTFS mount points. Can
anyone from Microsoft comment?
 
I still can't scan my drives. :-( I sure would like to get the program back
up and running again.
 
Tomorrow marks the one month anniversary of this post and still no
resolution. Besides this forum, are there other recommended support
alternatives?
 
How about this support channel ?

Free Limited Support - As a part of our commitment to the security of our
customers, Microsoft is offering two free support incidents relating to
Windows Defender on Windows XP and Windows Server 2003. Examples of valid
support scenarios are installation, configuration, definition update,
detection and removal errors. Please refer to the Windows Defender support
policy for more information
 
I called MS Support and used one of my free Windows Defender support requests
to report this issue. The result was an embarassing display of Microsoft's
support policies. After explaining the situation to the technical support
representative, the following is what was deduced by their department:

1. There are no knowledge base articles on the subject. I knew this of
course because I already checked.
2. There are no messages in the forums about the subject except my own. I
knew this also. Yet, they still suggested I try to resolve the issue through
the forums because they didn't have anything in their database on the subject.
3. They went so far as to confirm the issue as a bug, but they don't have an
"escalation policy in place" to notify the product development team. I was
given an e-mail address that was supposed to eventually get routed to one of
the teams, but all messages to that address bounce. After reconfirming the
address with support, it was deduced that it is no longer active. Support
declined to follow up to obtain the new address.
4. It was suggested that I sign up for Live OneCare because that support
group might be able to do more. So basically, I should pay Microsoft $50 for
the chance that I *might* be able to escalate through that channel. No thank
you.

The representative I spoke with was very polite and professional, so that
was appreciated. However, ultimately she and her management chose to hide
behind policy and perceived job roles rather than making an effort to bring
this defect to the attention of the appropriate parties. I find this very
disappointing and embarassing for Microsoft, particularly when the issue
deals with reporting a defect in one of their security products.

So in the end I was told, yes it's a defect in the software, but we don't
have a policy in place to notify the development teams of defects other than
the forums. That's why I'm back here, trying to raise awareness now of a
defect in Windows Defender, Windows Firewall, and apparently, the support
policies for those products.

I will summarize once again the issues below in the hopes that a member of
one of the product development teams sees this one day.

Windows Defender
---------------------
Issue #1: Partitions mounted as NTFS junctions only (no drive letters
assigned) do not show up in the custom scan list in the final release. They
did in Beta 2, and when I put it back on it works, so this is a defect
introducted in the final release.

Issue #2: When custom scanning any drive in Windows Defender, including C: I
get an error message "0x80508019: The file or drive you are trying to scan
does not exist on this computer. Choose another file or drive, and then scan
your computer again." I am fairly certain this is actually related to a bug
that I reported during Beta 1 that was resolved for Beta 2. Windows Defender
uses an alternate means of scanning registry hives. My registry hive is on a
partition that I've mounted as an NTFS junction to C:\Documents and Settings.
This allows me to keep the standard path while still having the files
physically located on a separate partition (for backup and other purposes).
Having my profile and registry hive on the separate partition is what seems
to cause this issue. Windows Defender is actually failing because it is
unable to scan the registry hive of my profile. Again, I had a similar issue
in Beta 1, it was fixed for Beta 2, and now it's back in the final release.

Windows Firewall
--------------------
Issue #1: Windows Firewall will not let you add programs to the exclusion
list unless they are on a partition with a drive letter assigned. I have
mounted a partition to C:\Program Files. This allows me to keep the standard
C:\Program Files path while still having all of my applications physically
located on a separate partition. Unless I also assign a drive letter to the
partition, Windows Firewall will not let me select an application for
exclusion under the NTFS junction.

Microsoft Support
--------------------
Issue #1: There is no escalation policy for application defects.
Issue #2: There is no standard online means for reporting application
defects. Some products benefit from Microsoft Connect, which is a step in the
right direction, but the product coverage on that site is still very small.
Issue #3: Staff is not able to identify shortcomings in policies and work
through a problem in spite of standard procedures not being in place. It is
very much a case of the mentality, "That's not my job, that's not what we do."

In conclusion, I realize that none of the application issues are so critical
as to represent a security risk other than perhaps the fact that the Windows
Defender issue is a blocking one. This means no anti-spyware from Microsoft
for me, even under Vista. The firewall issue I can work around, and there are
also third-party alternatives for that as well. I think the support issues,
however, will probably plague a larger number of users than just myself. And,
I know if I were a member of one of the development teams for those products,
I'd be very upset to learn defects weren't being escalated. If job roles are
the issue here, then I'd like to point out, it's typically development that
decides defect priority, not technical support.
 
Hello,

Does anyone know something new about this problem? I receive the same error
when I trying to scan any of my drives. It seems to be an unusual error
because I google it and dont found too many topics...

Thank you
