Daily scheduled scans always work, manual scans always crash


Recommended Posts

My firewall has all permissions for Malwarebytes on and I turn off Cryptoprevent properly and restart computer and even got rid of Avast from to add/remove control panel window and turned on Windows Defender instead.  I have Windows 7 Professional and I used the Malewarebytes repair tools and it  reinstalled a fresh copy of my Malwarebytes Premium.  Daily scheduled scans always still work but trying a manual scan always crashes immediately.  I have done this complete routine three times with the same results.  Anyone else experience this or know the fix?  Thanks!

Thanks for posting in the Malwarebytes for Windows Help forum.

If you are having technical issues with our Windows product, please do the following:

Malwarebytes Support Tool - Advanced Options

This feature is designed for the following reasons:

  • For use when you are on the forums and need to provide logs for assistance
  • For use when you don't need or want to create a ticket with Malwarebytes
  • For use when you want to perform local troubleshooting on your own

How to use the Advanced Options:

  1. Download Malwarebytes Support Tool
  2. Double-click mb-support-X.X.X.XXXX.exe to run the program
    • You may be prompted by User Account Control (UAC) to allow changes to be made to your computer. Click Yes to consent.
  3. Place a checkmark next to Accept License Agreement and click Next
  4. Navigate to the Advanced tab
  5. The Advanced menu page contains four categories:
    • Gather Logs: Collects troubleshooting information from the computer. As part of this process, Farbar Recovery Scan Tool (FRST) is run to perform a complete diagnosis. The information is saved to a file on the Desktop named mbst-grab-results.zip and can be added as an email attachment or uploaded to a forum post to assist with troubleshooting the issue at hand.
    • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.
    •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.
  6. To provide logs for review click the Gather Logs button
  7. Upon completion, click OK
  8. A file named mbst-grab-results.zip will be saved to your Desktop
  9. Please attach the file in your next reply.
  10. To uninstall all Malwarebytes Products, click the Clean button.
  11. Click the Yes button to proceed. 
  12. Save all your work and click OK when you are ready to reboot.
  13. After the reboot, you will have the option to re-install the latest version of Malwarebytes for Windows.
  14. Select Yes to install Malwarebytes.
  15. Malwarebytes for Windows will open once the installation completes successfully.

I am posting my first post above here on a friends computer just now but will provide logs when I get back home later today as request in the automated reply.

While I wait for the logs, Are you doing a standard scan and have you enabled any non standard options like rootkit scanning?

Here is the log file. 

I suggest uninstalling the following.

CCleaner ( Not recommended by experts any longer).
CCleaner Browser

CCleaner Update Helper

Dell Digital Delivery. Not needed and seems to be crashing in your error reports.

When doing Manual scans do the default scan only with out the additional items I mentioned checked. Do not bother to do full scans or the other drives.

Malwarebytes is not designed to function like normal AV scanners and uses a new kind of scan engine that relies mostly on heuristics detection techniques rather than traditional threat signatures.  Malwarebytes is also designed to look in all the locations where malware is known to install itself/hide, so a full or custom scan shouldn't be necessary, especially since the default Threat Scan/Quick Scan checks all loading points/startup locations, the registry, all running processes and threads in memory, along with all system folders, program folders and data folders as well as any installed browsers, caches and temp locations.  This also means that if a threat were active from a non-standard location, because Malwarebytes checks all threads and processes in memory, it should still be detected.  The only threat it *might* miss would be a dormant/inactive threat that is not actively running/installed on a secondary drive, however if the threat were executed then Malwarebytes should detect it.  Additionally, whenever a new location is discovered to be used by malware the Malwarebytes Research team adds that location dynamically to the outgoing database updates so the locations that are checked by the default Threat/Quick Scan in Malwarebytes can be changed on the fly by Research without requiring any engine or program version updates/upgrades.

After you have taken care of the above, run a standard scan and see if it works.

OK, I deleted those items,turned off those two unnecessary scan options and restarted computer and am using default settings with  'automatically quarentine maleware items found'on and now for some reason although it crashes upon manual scanning immediately, in about 5 minutes later the popup notificacation shows up with the same message as my screenshot here and that was the same in the past when it would only popup once a day for my scheduled scan, never before for a manual scan that crashed with that same resulting message day after day.  Upon clicking see results the program would open and immesiately crash, so I could never see the resulting items qurintined, which was probably somehow the same day in and day out for some reason..  I have been using this premium version since 2013 and would very rarely even find any results and those would be those PUP's.  This crashing though has been happening now for at least 6 months and I have been using this premium version on this Dell Windows 7 professional desktop since 2016 supurbly until about 6 monthes ago.  Thanks so far for your detailed responses so far Porthos.  Aloha, mauiart here on Maui

I see you're using one of the Group Policy methods used a few years ago in an attempt to prevent ransomware attacks. That's a difficult one in that if it's all correct in theory it should only be blocking items running from locations undesirable. If it's wrong anywhere though it can cause issues with legit programs running.

In this case our program is running and I assume you been using this policy for a long time now so for now we'll ignore it.

That said the logs do not reflect what you say about uninstalling items.

Please go to Control Panel, Add/Remove and uninstall all of the following. Then restart the computer and run Farbar to gather new fresh logs.


CCleaner Browser
CCleaner Update Helper
Dell Digital Delivery
Spybot - Search and Destroy



Please download Farbar Recovery Scan Tool 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

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press the Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it also makes another log (Addition.txt). Please attach it to your reply as well.

Thank you
