Had to cancel scan for rootkit after it took more than 11 hours?!?

Recommended Posts

So before i went to bed tonight i decided to do the most acurate scan as possible on my computer, covering everything. So i left it on overnight and after eating lunch the next day i came to the computer to see that it wasn't complete yet. Only somewhere around 700.000 files were scanned in this huge time spam. So i went into further research but i couldn't find much of a reason. I also use avast on computer and i may have forgotten to disable their shield temporarily, but i used to do this all the time with the default scan and it woudl'nt take any longer than 20 minutes. I'll attach the txt file i got from the scan report if it does help understanding the problem

Using the custom scan to perform a full scan of the system really isn't necessary.  Malwarebytes already checks all active threads and processes in memory in addition to all startup locations and loading points as well as the system, data, program, downloads, browsers and other areas where malware and PUPs like to install themselves/hide.  In fact, the only threat you might find with such a scan which might not otherwise be detected would be something like a PUP installer if you store old downloads in a non-standard location, however if you actually tried to install it, it would be detected by Malwarebytes' real-time protection in the Premium version and would be detected by the default Threat scan.

With regards to the scan taking so long, it did likely get hung up for some reason.  It is possible that one of the recent updates to Avast or Malwarebytes is behind it, however I don't know for certain; I do know however that Avast and Malwarebytes have had several compatibility issues in the past, though most of the ones I am aware of had to do with the web filtering in Avast and the Web Protection module in Malwarebytes.

To investigate the issue further, please provide diagnostic logs from the Malwarebytes Support Tool by following the instructions below:

  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

Thanks, are you able to complete a normal/default Threat scan by opening Malwarebytes and clicking the Scan button at the bottom center of the main page?  I just want to make sure that the default scan still works as that's the most important one.

Next, a new version of Malwarebytes has been released.  Please install it by opening Malwarebytes and going to settings by clicking the small gear icon in the upper right, then click on the Check for updates button under the General tab and allow Malwarebytes to download and install the new version and restart your system once the installation completes.

Once that is done, try another default Threat scan just to make sure it is still working correctly, then you can try another custom/full scan to see if it still gets hung up or not and let us know how it goes.
