Rootkit driver won't update

Recommended Posts


Though I checked the 'Scan for rootkits' box a few weeks back the Scan Logs always say 'Rootkits: Disabled'.  This may or may not be a problem, I don't know.

Earlier, though, when I logged on I got a message saying that MBAM couldn't update or load the Rootkit driver.  The first message gave me a code of 20023 (I think) and after the restart I had two messages giving me a code of 20025 (definitely).

Any help would be appreciated.

Hello and Welcome to Malwarebytes :)

Let's try this first....

  1. Please follow the steps in this pinned topic to uninstall your current version of MBAM and reinstall the latest build - MBAM Clean Removal Process 2x
  2. If that does not correct the issue, then please read the following and attach to your next reply the 3 requested logs - Diagnostic Logs(the 3 logs are: FRST.txt, Addition.txt and CheckResults.txt)
  3. NOTE: More info about v2.2.1 HERE; User Guide ONLINE; User Guide PDF; FAQ: Common Questions, Issues, and their Solutions

Please let us know how it goes.

PS: There is a bug in the program where the logs do not report the status of MBAM at times...

Thank You,

This may or may not be helpful. My scan logs show ROOTKITS : DISABLED during my scheduled "HYPER SCAN".

I have my MBAM Premium scheduled to do a Hyper Scan everyday and a Threat Scan (full scan) once a week.

Rootkits are only ENABLED during a TREAT SCAN.

A HYPER SCAN is a quick scan and Rootkits are DISABLED.

When checking your SCAN LOGS double check the SCAN TYPE displayed in the SCAN LOG.

Hi, @davidmg:)

Thanks for your suggestion.  However, the issue you describe is a bit different from the one reported by @Pssyche.

You are correct that there is a logging issue with certain scan settings -- this is known to developers and is on a list to be fixed.
And it's also true that there are 2 places to enable anti-rootkit scanning (a "global" setting and an Advanced setting in the scheduler).

However, the OP reports a 20025 error -- the first step for troubleshooting that error is the clean reinstall suggested by @Firefox.

So, @Pssyche, please follow that advice and let us know how it goes.

Thanks to all,

Thanks for the replies, guys.


Funnily enough, the log for the unscheduled scan that ran (I say 'that ran' because I didn't ask for it, at least not deliberately) just after I had this issue shows that Rootkits was/were Enabled.  I shook my head at this, thinking 'They're going to blacklist me as a false-alarm specialist' but the following two or three scheduled scans have shown Disabled.


davidmg: I was hoping your suggestion would be the answer, but I'm definitely running Threat Scans.


Which means I'm going to have to go the route suggested by Firefox and daledoc1, as daunting as it is.


I will do it and let you know what happens.


Thanks again for your time and your help.

You might also try the following since the setting for scanning for rootkits under Detection and Protection does not necessarily apply automatically to scheduled scans:


  • Open Malwarebytes Anti-Malware and click on the Settings tab

  • Click on Automated Scheduling on the left

  • Select your scheduled scan having this issue to highlight it and then click on the Edit button at the bottom

  • In the dialog box that opens click on the Advanced button and ensure that the checkbox next to Scan for Rootkits is checked and if it is not then click the box next to it to check/enable it and then click OK at the bottom

    If that does not resolve the issue then proceed with the instructions above from the others.

Hi exile360

Apologies for the slow reply (very busy) - just wanted you to know that your fix worked, and the other problem hasn't reared its head again either, so everything's looking good.  

Also want to add that MBAM is one of the best things I've ever bought.

Thanks to all of you for your time and help.
