[StormofThunder]

Bitdefender update went out this morning and killed something.

did a restore to earlier date on one system. worked fine again.

once the update hit. broke.

Oh joy. I'll try to do a system restore.

Has anyone contacted them, just curious?

 

[ChrisDJ]

Found a fix: Replace user32.dll

I was in Windows 7 hell for the past 3+ hours. Flashing windows screen, no login prompt unless in safe mode. Event log said logonui.exe was having a problem with a call from user32.dll. However the Startup repair and registry Repair utilities failed to find any problems. Found the fix: boot from the Windows 7 recovery disc, go to command prompt and replace the user32.dll file on the computer. Reboot and voila! Everything works again!

(and for the record, I use BitDefender too!)

Lucky me I always have system restores fail on me and not change a thing. Now what, bitdefender?

Work around

We found a temp fix. In BitDefender, if you exclude both:
C:\Windows\system32\LogonUI.exe as a process
C:\Windows\system32\USER32.dll as a file

When the policy updates it should be fixed.

After restarting user computers, they no longer have the problem.

Not really a fix for us because we are looking at a lot of affected systems right now spread over a wide area (multiple locations).

 

[milanetsky]

so any solution about bitdefender?

Sadly I don't have a windows 7 recovery disk. Is there such a thing as a downloadable version of it? The dll I mean

How do you start up and do that with Bitdefender on windows safe mode, since its the only thing that we can use?

I noticed another thing, most of you have ASUS computer. There was a similar incident a few years ago with DELL computers which turned out to be a program called "FastAccess". Look in Windows error reporting logs for a "Faulting module" to try and determine the root cause, example: Fast access error? - Productivity Software Forum - Software & Operating Systems - Dell Community

Run Windows 7 Startup Repair from the Windows 7 CD.

I checked out the link in jtmoney528's post and BitDefender is sending out an update to fix the issue.

Don't have one, lost it ages ago, and I believe I can't create a other one if this is my only Windows PC. I can't recall, sorry, but can you do it if you have someone else's PC? I forgot about these worked as I haven't needed one in a long time.

Will we be able to apply the update while being in safe mode?

 

[phiquach]

Okay, we got it a fix here.

We disabled AVC and so far no issues

 

[SonicClang]

So I take it you're a home user? I don't know what to tell you on that one. I think your best bet is going to be to call BitDefender and have them help you since they're ones that hosed your computer.

I also disabled AVC and it worked, I have re-enabled it after they posted up that the fix was out, now I am waiting for an end user to test it out.
