Web Protection blocks ALL DNS

Recommended Posts

Malwarebytes v3.1 (current version) on Windows, blocks ALL DNS lookups if Web Protection is ON (Default). I have now found this on a number of client PCs. Concequently I have removed Malwarebytes as this situation is unacceptable. We had spent hours trying to fix web browsing, until we discovered that the culprit was Malwarebytes!

 NOT HAPPY! When the very tool that is supposed to give you protection, breaks the system.

Yes and No. I would if I could, but I can't.

My customers, just needed to be able to work, so I removed Malwarebytes immediately, which fixed the problem. So I do not have any debugging information available.

Why don't you try to replicate the problem on a test machine? I had it happen now on 3 different sites, so it wasn't unique, and you should be able to see it. We were on Windows 7 64bit.

Because we do not know about every bit of other software on that machine. And that is just the beginning. With over a million users don't you think Malwarebytes would have seen this issue a million times before?

issues can ONLY be fixed if the proper logs/ tests can be run.

I am personally sorry you had issues. But getting help is a 2-way street. I personally have 100's of clients with zero issues.

I am happy that you don't have issues. I wasn't asking anyone to fix mine, I just reported it in case anyone else had experience with similar problem.

When I have a customer situation (case in point, the Accounts PC was unable to connect to their cloud based accounting program), my priority is to get the customer situation resolved asap, rather than start a possibly, long winded interchange with support.

If you don't want to test the problem, because your PCs are working, that's fine by me. :)

Have a wonderful day, and as Mr. Spock used to say, "Live long and prosper".

Then I will have this moved to the comments and suggestion in stead of this help area.

Hello @pszilard

Sorry you're having issue but I can assure you that no we do not block DNS. Here is an example from my own box running the latest version of Malwarebytes 3


C:\Windows\system32>nslookup google.com
Server:  google-public-dns-a.google.com

Non-authoritative answer:
Name:    google.com
Addresses:  2607:f8b0:4007:80c::200e


If we were blocking DNS in any way that IP address would not have come back. As @Porthos has suggested, we'd be more than happy to assist you in tracking down the real issue if you like.

Thank you

@pszilard we would need the following logs from the Windows 7 box having this issue, can you provide those so we can review them?

Let's try and get some logs first so the team can review them and see if they can tell what may be causing your issues....

  1. FIRST: Create and obtain Farbar Recovery Scan Tool (FRST) logs
  2. Download FRST and save it to your desktop
    NOTE: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit
  3. Double-click to run FRST and when the tool opens click "Yes" to the disclaimer
  4. Press the "Scan" button
  5. This will product two files in the same location (directory) as FRST: FRST.txt and Addition.txt
    NOTE: These two files will be collected by the MB-Check Tool and added to the zip file for you
  6. NEXT: Create and obtain an mb-check log
  7. Download MB-Check and save to your desktop
  8. Double-click to run MB-Check and within a few second the command window will open, then click "OK"
  9. This will produce one log file on your desktop: mb-check-results.zip
  10. Attach this file to your forum post by clicking on the "Drag files here to attach, or choose files..." or simply drag the file to the attachment area

Thank You,
