NOD32v4 interfering with Windows Update

I'm using Eset NOD32 anti-virus 4.0.437.0 on Windows Vista Ultimate 32-bit SP2. Since I installed NOD32v4 I have noticed that some Windows Updates do not install, causing error 80072F78. When disabling NOD32 the update installs successfully. I most recently had this with update KB973874, a IE8 Compatibility View List. I have noticed this problem affecting the Windows security updates too.

Has anyone else come across this problem?

Detailed NOD32 info:

I have come a crossed many Windows update related problems. I don't think NOD32 is the one to blame here. Your error means 'ERROR HTTP INVALID SERVER RESPONSE'.

Here is a topic about the error you have.

I also use this script when encounter Windows update related problems:

Code:

Echo This batch file will Force the Update Detection from the AU client: 
Echo 1. Stops the Automatic Updates Service (wuauserv)
Echo 2. Deletes the LastWaitTimeout registry key (if it exists) 
Echo 3. Deletes the DetectionStartTime registry key (if it exists) 
Echo 4. Deletes the NextDetectionTime registry key (if it exists)
Echo 5. Restart the Automatic Updates Service (wuauserv) 
Echo 6. Force the detection 

@echo on
net stop wuauserv

Picked it up on a WSUS list once, modified a few things and it has helped me resolving lots of errors I have seen.

 

You can also try disabling detection of potentially unsafe/unwanted programs and see if the updates install. It worked for me. Some may argue against doing that, but it has not hurt me, so I leave it turned off.

 

Thanks, I'll give these suggestions a try on Tuesday when the patches come out.

 

Found the cause - for some reason, svchost.exe was selected in the Web Access Protection Active Mode list. Unchecked it and Windows Update is happy again.
