Problems with sysfer.dll (Code integrity)

Created: 19 Jun 2008 • Updated: 21 May 2010 | 2 comments
I run windows vista premium on at dell xps-420 and get faults related to sysfer.dll in the logs. More precise I get the follow description in codeintegrity:

Code Integrity is unable to verify the image integrity of the file \Device\HarddiskVolume3\Windows\System32\sysfer.dll because the set of per-page image hashes could not be found on the system.

I get similar warnings with respect to WpsHelper.sys (and af few others):

Code Integrity determined an unsigned kernel module \Device\HarddiskVolume3\Windows\System32\drivers\WpsHelper.sys is loaded into the system. Check with the publisher to see if a signed version of the kernel module is available.

I seems to be a problem when I buy and download WMA files. When mediaplayer try to get the DRM license from I get an error and the log event related to sysfer.dll.

When I remove SEP I have no problems getting the license and can play the music.

Does any experience the same and maybe have solved the problem?

I also have this same problem running SEP MR2_MP1 on windows server 2008 standard.  The same two files give these messages upon boot.  Other than the messages everything appears to be working as expected.  Anyone found a solution to this yet?

Make a new install package without network threat protection component, the file sysfer.dll is part of this. It happened to me with other software and I fixed by this way.

I hope it work for you.
