Malwarebytes disabled -- MBAM_ERROR_LOAD_DATABASE (0.0)

[EastYork43]

1. I have had a licensed edition of Malwarebytes for over a year. No problems. This morning it stopped working. I'm not very tech-savvy, so unsure what to do.

I suspect an update to my AVG Anti-virus program yesterday is interfering with the Malwarebytes, but that's only a guess.

2. Yesterday (Sep 3rd) everything was fine. Here is the protection log:

09:37:32 admin MESSAGE IP Protection started successfully

10:37:00 admin MESSAGE Scheduled scan executed successfully

3. I updated my AVG Anti-virus program in there. AVG version 8.5.441. Virus data base 271.1.1/3111 (last updated 3 Sep 10 10:04 am).

4. Here is the log of the automatic Malwarebytes quick scan done yesterday (after the AVG update) (everything was fine):

(I also ran a full scan yesterday, with the same results -- no problems.)

5. I shut my computer down at 11 am yesterday, just a few minutes after the full Malwarebytes scan was completed.

6. I turned my computer on at 9:36 am today. Here's where the problem started.

Here's today's protection log:

protection-log-2010-09-04.txt (saved 9:47 am)

09:37:29 admin ERROR UtilityReadFile failed with error code 32

09:37:30 admin MESSAGE Protection stopped

09:47:32 admin ERROR CryptDecrypt failed with error code -2146893820

09:47:33 admin MESSAGE Protection stopped

I didn't know anything was wrong at first, until an error message from Malwarebytes popped up, saying something like "protection has stopped". (I was on the internet site of a major bank at the time.)

So I tried to click on the Malwarebytes desktop icon to re-start protection. I got a different error message:

An error has occurred. Please report this error code to our support team.

MBAM_ERROR_LOAD_DATABASE (0.0)

7. I re-booted the computer. No Malwarebytes icon in the lower right hand corner of my screen (where it usually is). The Windows Task Manager does NOT show any "mbam" file, which is usually running.

When I click on the desktop Malwarebytes icon, the same error message appears:

An error has occurred. Please report this error code to our support team.

MBAM_ERROR_LOAD_DATABASE (0.0)

8. Since everything was fine when I shut the computer down yesterday, and nothing had happened except the update to AVG (and maybe some automatic updates to some other programs), I'm wondering if another program's update is interfering with Malwarebytes.

Any ideas?

(I can e-mail my Malwarebytes ID & key if needed, but obviously shouldn't post that on a public forum.)

AVG has been known to interfere with Mbam and target it as a threat at times unfortunately

Do you have the internet security version of AVG or just the AV?

As a side note, please use the "ADD REPLY" button located at the bottom of the page when replying.

I just have the free version of AVG. I think it's pretty basic. But it has what they call a Link Scanner and a Resident Shield. I see various AVG applications running in the Windows Task Manager all the time.

I was just wondering because I used to use AVG Internet Security and Malwarebytes in real-time together and they (surprisingly to me) worked nicely together.

Have you added exclusions? If not, I would definitely recommend doing so (Section H):

Also you might consider doing a clean install of Malwarebytes after adding exclusions (AVG might have wiped out something in Malwarebytes and it would be a good idea to do a clean install):

Windows XP:

• Click on Start and select Control Panel
  
• Open Add/Remove Programs
  
• Uninstall Malwarebytes' Anti-Malware
  
• Restart your computer very important
  
• Download and run mbam-clean.exe from here
  
• NOTE: If you get SHGetValue failed with error code 0, that only means that the tool has nothing to perform, continue on with the next step....
  
• It will ask to restart your computer, please allow it to do so very important
  
• After the computer restarts, temporarily disable your Anti-Virus and install the latest version of Malwarebytes' Anti-Malware from here.
  Or here, (this is my preferred download location): http://majorgeeks.com/Malwarebytes_Anti-Malware_d5756.html
  
  • Note: You will need to reactivate the program using the license you were sent via email if using the Pro version
    
  • Launch the program and set the Protection and Registration. Then go to the UPDATE tab if not done during installation and check for updates.
    Restart the computer again and verify that MBAM is in the task tray if using the Pro version.
    

  Let me know if those help or not. If not, unfortunately those are my only ideas but someone else should be able to help you

See Section H here: http://forums.malwarebytes.org/index.php?showtopic=10138 Let us know how it goes

Thx for the tips mountaintree16 & yardbird. I followed them, and the problem is gone.

When I updated my AVG anti-virus program yesterday, I noticed that I'd never authorized its Resident Shield to scan tracking cookies. So I checked that box. I'm wondering if that caused the problem.

Anyway, with the exceptions you suggested entered into AVG -- which does show up in its Resident Shield section -- I'm not experiencing any interference with Malwarebytes.

Thx for your help. Much appreciated!
