Hello.

I don't know if this is a problem or not. Recently, I've tried to scan my device without the rootkits option. The total time took only around 40 minutes with 437k items scanned. But now I tried to make sure another scan with an additional option for rootkits, it's already 16 hours and still ongoing now. Should I stop it?

Hi,

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:

Spoiler
  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.

Hello @AryYulianto and :welcome::

What you are seeing is perfectly normal. Adding the rootkit element to any scan will dramatically increase the time to completion. If you have let the scan run that long, nothing but time is lost to run to the end.

That is why the rootkit element is not part of the default, nor is it recommended.

Was this a custom scan or a standard threat scan???

I don't remember, probably a custom scan. The rootkits option is off by default on the standard scan, I think. I just get dozens of viruses and tried to do the scan much more intensively by approving any options in the advanced scan on there. And now I can see why this option is off by default.

So, is there any thread about this topic? Something like when I should use this option, what's the purpose or how, anything about it.

No,

It is recommend rootkit be turned on only where there is an issue for removing something with the normal scan. Rootkit is slightly more dangerous as it has to disable some whitelisting to remediate some rootkits.

Maybe once a month if really want to use rootkit. But honestly, we rarely see rootkit files anymore and the newer engine can remove most of them anyways even without rootkit on.

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 on any sort of frequent basis , 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.

If you need a flat file scanner to check archived data/drives, I would recommend using one of the many available free AV scanners such as Kaspersky's Virus Removal Tool, ESET's Free Virus Scan, or even the built in Windows Defender that ships with Windows 8/8.1 and Windows 10.  Links to the first two scanners I mentioned can be found below:
