Threat Scan Scanning for over 5 hours

Recommended Posts

This moring an automatic update started followed by a threat scan.
This usually takes a couple of minutes to finish, but today the scan has been running for over 5 hours now and it still hasn't finished.
It seems the scan is stuck on a .cab file (C:\ProgramData\Package Cache\{60D5EF2A-4E0C-2C30-38F6-59C26E134F4A}v8.59.25584\packages\Windows_SDK\58314d0646d7e1a25e97c902166c3155.cab) The .cab file is only 17MB so it shouldn't take this long to scan it.

It seems something is keeping malwarebytes from correctly accessing or reading the file, but there also doesn't appear to be a timeout in malwarebytes, which makes it so it can't get stuck on a single file.
A skip button would be nice as well, as all I can do now is pauze or cancel.
Pauze is useless in this case, and cancel makes it so the rest of my computer doesn't get scanned.

If you want I can add the file as an attachment so you can take a look at it.

A reboot, would probably fix the issue, you can try rebooting and then running another scan to see what happens.  The file that is displayed my not actually be the file its stuck on.

Can you provide some logs so we can have a look at what may be happening? 

  1. Please read the following and attach to your next reply the 4 requested logs - Diagnostic Logs (the 4 logs are: mbam logs zipped, FRST.txt, Addition.txt and mb-checkResult.txt)
  2. NOTE: More info about the latest Malwarebytes 3.0.6 CU4.1 HERE; MB 3 User Guide ONLINE; MB 3 User Guide PDF; MB 3 FAQ: Malwarebytes 3.0 - Frequently Asked Questions

Please let us know how it goes.

Thank You,

Hello @RagingRaven

You do have the following potential issues. Nothing wrong with a proxy, as long as you're aware of it and have set it up yourself and no malware.

ProxyServer: [S-1-5-21-3921867960-3328932981-4260551549-1001] => proxy1.eu.webscanningservice.com:3128

HKLM\SOFTWARE\Policies\Microsoft\Internet Explorer: Restriction <======= ATTENTION

Not sure if you're aware, but the logs also indicate the computer is currently being used to pirate and steal software from Adobe.



There are some other errors in the logs that can potentially be affecting overall computer performance. Including our own program, which crashed.

Can you try turning off rootkit scanning to see if that helps? If it does, can you please perform the following instructions so I can verify something?

  1. Press the Windows key + R
  2. In the dialog box that pops up, type cmd and click Ok
  3. In the window that pops up, type compact /compactos
  4. Please post the results of that command (a screenshot is fine)

@AdvancedSetupThe proxy was a test for one of my customers some time ago, but it was inactive, so shouldn't be an issue.

I'll run a checkdisk later today (when I don't need my computer) and post the results.

@dcollins Turning off rootkit scanning probably won't help as the issue seemed to be fixed by doing a reboot. Also before it never gave me an issue.
I do believe AdvancedSetup is on to something with the disk having an issue though.
I did try your command though, it said: The system is in the Compact state.  It will remain in this state unless an
administrator changes it.

I'm guessing that's the default state in Windows 10, as I've never changed it.
