malwarebytes error

[NelliO]

I'm having a real problem. I received an error message - MBAM_ERROR_MISSING_FILE (2.0 mbabmswissarmy.sys) - so I went online and found I should uninstall MB and reinstall it. I did this and on the flash scan it found a file called swissarmy and recommended that I delete it. I agreed.

But I'm still getting the error message and there seem to be no files available for MB even though it is listed in the program files list. Can anyone help please?

I have a Dell Inspiron laptop with Vista, FF browser and use Avast AV. I am also a licensed MB user.

Please try the following to see if it helps:

Windows Vista and Windows 7:

• Click on the Start button and select Control Panel
  
• Click on Programs and Features
  
• 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
  
  • 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. Now setup any file exclusions as may be required in your Anti-Virus/Internet-Security/Firewall applications and restart your Anti-Virus/Internet-Security applications. You may use the guides posted in the FAQ's here or ask me and I'll explain how to do it.
    

Then Follow these instructions:

Please exclude the following files from your antivirus:

Note: If using a software firewall besides the built in Windows Firewall you'll need to exclude them from it as well

• C:\Program Files\Malwarebytes' Anti-Malware\mbam.exe
  
• C:\Program Files\Malwarebytes' Anti-Malware\mbamgui.exe
  
• C:\Program Files\Malwarebytes' Anti-Malware\mbamservice.exe

Note: If using a software firewall besides the built in Windows Firewall you'll need to exclude MBAM.EXE from it as well

Note: Once that's done, please make sure that if either of those programs has any sort of web filter, that you add the following as a trusted site:

Twice I uninstalled and reinstalled MB and finally all seemed to be ok though I wasn't asked for my license number which surprised me. Today I saw your answer and have followed your instructions but whether anything has changed I don't know. I haven't had the error message again so I hope it's all right now. I didn't understand the bit of your reply regarding filters but I don't think I have any. If I do where are they?

I couldn't add your exclusions to Windows Defender because for some reason the appropriate box is inactive though Defender is working.

Thank you for your help.

NelliO: Do you have any AV installed in which case please follow the instructions Firefox has given, if you also have MBAM Pro then you don't need Windows Defender and could completely disable it, here is how you could accomplish http://forums.malwarebytes.org/index.php?showtopic=8279

These are my personal views, you may want to wait till Administrators/Moderators/Trusted Advisors could second!

[NelliO]

I don't know of any Firefox instructions. Where would I find them?

And, yes, I do have AV installed - Avast - but I don't have MB Pro so don't need to disable Defender. Or do I?

As far Firefox is considered - he is our Trusted Advisor (Post #2). Having MBAM licensed version and Pro are one and the same thing

Sorry, I misunderstood. I thought you were referring to the FF browser which I have. Now I have disabled Defender too.

Thanks a lot.

I have avast! V5 Free on my Windows 7 system and Pro on my XP Pro system and I have not had to add any exclusions to Windows Defender in Windows 7.

I do update Windows Defender daily and have it run a Quick scan in the morning.
