[solved] Warning: Deleted unsigned file

[solved] Warning: Deleted unsigned file

Postby OlegK » 10.03.2011, 15:35

Hello!
During the download process, at the stage of file signatures verification, I get strange warnings about deleting some of the just downloaded files, including even the wmp11 distribution.
First, I run downloading wxp rus on a clean, just unpacked distribution of ver.6.81. Here is a fragment of the log:
Code: Select all

Afterwards, I run downloading wxp enu and get this:

Apparently, KB968930-x86-ENG has been downloaded and deleted once again, and even WMP11 did not escape the fate.
Can anyone give me a hint of what is going on?

Hi OlegK,

an unsigned patch file is suspicious, thus it's deletd by WOU if verification is enabled.
To avoid deletion of unsigned files, just turn off verification.

Thanks, Torsten!
I understand that it is not a bug in WOU. But still, the loss of certain patches, including even WMP11, seems a very serious side effect from turning on verification. Maybe, the user should be warned when turning on this option. Or, maybe, there is some workaround like requesting the missing signatures from some reliable source...

Normally ALL Microsoft patches are signed, I've yet to hear about an unsigned one.

Note that requesting signatures is not possible, they are firmly embedded within the PE executable.

To be specific, this hotfix:
http://download.microsoft.com/download/ ... 86-ENG.exe
displays a valid signature when I download it manually and right-click on it.
But it gets deleted by WOU immediately after automatic downloading, with "Warning: Deleted unsigned file ..." message.
By the way, it is a statically defined update.

Hi OlegK,

actually, this is not the case at my place:

Code: Select all

14.03.2011 13:23:38,04 - Info: Determined statical update urls for wxp glb

...and WindowsXP-KB968930-x86-ENG.exe is (still) present in ...\client\wxp\glb...

Hmmm, maybe it's time to get a Linux-based Offline Virusscanner and to scan your system for infections. Just to be sure it's not a side-effect of an infection.

Doesn't it depend on the version of sigcheck?
The following is what I get when I check manually the hotfix which was downloaded also manually (download link is in my previous post), without the use of WOU.

I get the same as harry does, and that's what shows your problem - you get an "Invalid Chain" where we get a "Signed".
File properties at my place:
- WindowsXP-KB968930-x86-ENG.exe: 6.156.064 Bytes (MD5: 9859a26d5e72bbb0685af813b409d99d)
- sigcheck.exe: 220.024 Bytes
