Scheduled Scan with Malwarebytes 4 Take Longer. Why?


Recommended Posts

Hello all,

I've noticed  that on my laptop, scheduled take hours to complete after upgrading to Malwarebytes 4. This is not the case on my desktop, although I think the scans still take a little longer than they did with 3. This is not causing any problems for me, but I am curious as to what has changed to cause this. Is this deliberate or is this a bug?

Greetings,

It depends on the type of scan you are running, but if it is the default threat scan then it definitely shouldn't take hours to complete, only minutes.  It is possible that there is a conflict or issue that is causing Malwarebytes to take longer than normal to scan.  If you use an AV in addition to Malwarebytes this could be the reason, and if so then please be sure to exclude the items listed in this support article from your AV's real-time protection to help prevent conflicts.

If that does not resolve the issue then please do the following and we will investigate the issue further:

  1. Download and run the Malwarebytes Support Tool
  2. Accept the EULA and click Advanced tab on the left (not Start Repair)
  3. Click the Gather Logs button, and once it completes, attach the zip file it creates on your desktop to your next reply

Also check to see if manual scans also take longer than normal.  To do so, open Malwarebytes and click the Scan button on the main dashboard and wait for the scan to complete.  If it also takes hours then please do the following:

Create a Process Monitor Log:

  • Create a new folder on your desktop called Logs
  • Please download Process Monitor from here and save it to your desktop
  • Double-click on Procmon.exe to run it
  • In Process Monitor, click on File at the top and select Backing Files...
  • Click the circle to the left of Use file named: and click the ... button
  • Browse to the Logs folder you just created and type MB4 Log in the File name: box and click Save
  • Exit Process Monitor and open it again so that it starts creating the logs
  • Open Malwarebytes and perform a scan.  Once it gets stuck, let it run for a bit longer (30 seconds or so after it gets stuck should be sufficient) then terminate the scan
  • Close Process Monitor
  • Right-click on the Logs folder on your desktop and hover your mouse over Send To and select Compressed (zipped) Folder
  • Please attach the Logs.zip file you just created to your next reply, or if it is too large, please upload it to WeTransfer and select the option to send the file as a link from the options menu available by clicking on the circular ... button on the page and provide us with the link to the file

Please let us know how it goes and if necessary please provide the logs and information requested above.

Thanks
