IE 11 adress bar search term triggers MBAM exploit block

Recommended Posts

I won't go into details on to why I was searching this term, but when i typed the word endrimitriosis into the address bar of ie on windows 10 FCU 16299.19, IE suddenly closed and MBAM showed a exploit block message. I tried using the term in the search bar of IE as well as in edge, and no alert was triggered. I also tried other search terms an even misspelling the word in the address bar of IE. the only time the exploit block was triggered was when i used the word endrimitriosis. I don't know why this particular term triggers an exploit alert, but it seemed like an important discovery, so i thought i would ask a bout it here.

no the issue does not appear if any other term is used. and the issue does not occur with the search bar... it is when the address bar is used to perform the search. if you use the search bar, nothing happens except for the search. I have included two images. screenshot (62) is the one you asked for, while screenshot (63) demonstrates where i am performing the search.

i tried the same address bar search in both Edge and Chrome, and only  doing in IE triggers an exploit block alert.


I tried switching the search engine from google back to bing, and the issue still occurs

I also tried removing (one at a time, since there has to be a default search engine) both bing and google as search engines, and re adding them from the  microsoft IE galllery page (https://www.microsoft.com/en-us/iegallery)


also tried a repair install, problem still exists

You can, based on your symptoms I have a feeling it will work properly since Exploit Protection is what's causing you're issue.

Can you try removing Malwarebytes entirely and installing standalone anti-exploit to see if the issue persists? You can download that from here:

turning off mbam exploit protection and performing the address bar search with the term endomitriosis the broswer performs a search as expected.....  why is there a exploit warning for this term when an address bar search is performed?

Alright, let's go ahead and re-install Malwarebytes, then please follow the instructions below so we can get some debug information:

  1. Please download the files from this link:
    • https://malwarebytes.box.com/s/kzoo8u6jq7n82e0uji909y7pnuozx77z
  2. Right click Malwarebyes in the system tray and choose Quit Malwarebytes
  3. Extract the contents of the ZIP to a sub-folder in your Desktop.
  4. Copy the files mbae.dll and mbae64.dll and paste them to the C:\Program Files\Malwarebytes\Anti-Malware\ folder.
  5. Copy the files mbae.sys and mbae64.sys and paste them to the C:\Windows\System32\drivers\ folder.
  6. After you replace the files, double click the desktop icon to start Malwarebytes again
  7. Reproduce the problem and collect and send back to us these files:
    • C:\ProgramData\Malwarebytes\MBAMService\logs\mbae-default.log
    • C:\ProgramData\Malwarebytes\MBAMService\logs\MBAMSERVICE.log
    • C:\ProgramData\MBAE_minidumps\

sorry, was busy yesterday and wasn't able to do the next step until today.


I added the files as directed, but when MBAM was restated, the exploit protection would not turn on. I restarted MBAM a second time, and it was on but it turned off after about a few seconds. is this what should be happening?

here is the log files you asked for, but i have a feeling they won't be very useful since antiexploit is not working anymore, since i added the files you had me d/l.


included in the .zip file is the mbamservice.log, and mbae-default.log the directory C:\Programdata\MBAE_minidumps does not exist, so naturally, i can not add them to the the .zip file
