Latest version of Malwarebytes (free) runs LONG time

Recommended Posts

I've tried twice to do a scan with MWB 4 and the file counter stops around 137,333 even though the timer advances. I've let it sit for quite a while and cancelled after 3.5 hours. I didn't see any way to display what (file) is currently being scanned.

Is this normal and should I just let it go for as long as it takes?

Thank you.

Greetings,

According to your logs you are also running Avast Antivirus.  Please exclude the items listed in this support article from Avast's real-time protection to see if that helps.

Please let us know how it goes and if the issue is now resolved or not.

Thanks

It did not work. I added all the exceptions in the document but it has been on the same item count for over an hour. See images.

OK, please do the following so that we may determine precisely where it is getting stuck:

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

Thanks

Thanks.  I took a look at your logs and so far I've singled out this file which the scan spent several minutes on:

C:\Windows\WinSxS\FileMaps\$$_syswow64_21ffbdd2a2dd92e0.cdf-ms

Please try excluding that file in Malwarebytes to see if it makes any difference.  To do so, open Malwarebytes and click on the Detection History area on the main dashboard then select Allow List and add a file exclusion for the file listed above then try running the scan again to see if that makes any difference.

Please let us know how it goes.

Thanks

You guys are fast!  Thanks for the help, it's appreciated but that was not it. Stuck for several minutes on same item count before I cancelled.

What happens if you disable Avast, does that make any difference?  It's possible that Avast is slowing it up still even with exclusions for some reason.

I disabled Avast Behavior shield and File shield and now it's worse. Stuck on item 3979 and has been scanning startup items for 12 minutes now.

This is after a fresh reboot. Earlier, MWB was stuck on Checking for updates until I killed it and rebooted.

This is very strange. I've had NO problems before messing with MWB not that I'm saying it's the cause. Today, my PS\2 keyboard stopped working. Had to swap it out with a different (USB) one. Either I'm being cursed or something very odd is starting to happen to my old PC.

That is strange.  It is possible that the drive is failing and these issues with Malwarebytes are just an early sign of it.  You can try a clean install of Malwarebytes to see if that makes any difference, but I'd also definitely recommend backing up any important data on another drive or some external media just in case it is failing hardware.

To do the clean install please use the Support Tool as detailed below:

  1. Run the Malwarebytes Support Tool
  2. Accept the EULA and click Advanced tab on the left (not Start Repair)
  3. Click the Clean button, and allow it to restart your system and then reinstall Malwarebytes, either by allowing the tool to do so when it offers to on restart, or by downloading and installing the latest version from here

I've done a fresh install of MWB when I initially had problems with it so I don't think that's it.

And my hard drive seems ok (see below)  so I'm very disappointed because it's a great program and confused because I don't know what the problem is.

Thank you for all your efforts!

Alright, just to rule it out completely please try removing Avast from the system, restarting, then reinstalling Malwarebytes and trying to run a scan to see if it works properly.  Please use the Avast uninstall tool found here.

Perhaps that is it but, since I don't think I have a problem, the additional effort is just not worth it to me. Besides, you'd think it would have  been quickly discovered if AVAST causes this big a problem. Again, thank you sincerely for your help.

Sure, I'm just trying to rule some things out.  We have seen some issues with Avast in the past, though nothing for quite a while.  Still, it might be worth a shot just to check as it may be a combination of things causing it, and a fresh install of Avast might actually correct it if it is related (like if one of Avast's drivers or other components isn't up to date for any reason).  I also noticed CryptoPrevent is installed.  It's possible that its background monitoring/service might be slowing things down during scans, or a combination of it along with Avast and/or some other software running in the background (GlassWire, Macrium Reflect, SUPERAntiSpyware etc.) so that's another possibility.

Another possibility that we should rule out is that there might be some kind of malware on the system causing the issue.  I noticed a lot of policy restrictions for various file extensions and programs in your logs and unless you created them or know what software did, the system should definitely be checked for threats.  To have one of our malware removal specialists check the system to ensure it's clean please follow the instructions in this topic and then create a new topic in our malware removal area by clicking here and one of our malware removal specialists will analyze the logs and let you know if anything malicious or suspicious is present on the system and advise you on how to remove it if found.
