Full scan crashes GUI but quick scan works. Go figure...

Recommended Posts

Hello Community,


Until recently MalwareBytes has worked flawlessly, however now it keeps crashing on full scans.


I am able to perform a quick scan and with no infections detected.  However when I switch over to a full scan MalwareBytes eventually crashes.  It takes out the GUI so that all over programs just give .dll errors.  The issue corrects itself after I reboot the system which sometimes Windows will gracefully restart and sometimes it is a hard reset.


I have run a full CHKDSK on ALL partitions.  I turn off other security programs such as Webroot SecureAnywhere my main realtime protection, when running the scans.   SecureAnywhere will do a full file scan with no problems or errors.


I have done a full uninstall and reinstall of MalwareBytes.  I am running version on Windows XP SP3 with all current updates applied short of things like Windows Search, Bing desktop, and MS anti-malware tool (garbage).


What leads me to believe it is something in MalwareBytes, at least on my machine.  As I stated earlier SecureAnywhere performs full file scans of all files on the hard drive, across all partitions, with no errors or crashes or malware detected.


So I thought I would reach out and see if anyone has any other ideas or thoughts, as I am out of them at this point.


Thank you!

Hello and welcome, solaris: :)
Until one of the staff arrives, a couple of thoughts:

If you are still having problems after that, please follow the instructions below and reply back to this topic with the requested logs ATTACHED to your next reply.


  • Checkresults.txt from mbam-check
  • A couple of protection logs, if you have them
  • DDS.txt from DDS
  • Attach.txt from DDS


These will provide the MBAM staff with a bit of information that will help them to pinpoint the cause and the solution for you.




Step 1 -- Create an mbam-check log:

Download mbam-check.exe from HERE and save it to your desktop.
Double-click on mbam-check.exe to run it, it should then open a log file.
Please attach to your next reply the CheckResults.txt file which should now be located on your desktop.

Then, if you can, please also upload your 3 most recent Protection module logs:

In Windows XP, these logs are located in: C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs
In Windows Vista/7/8, these logs are located in: C:\ProgramData\Malwarebytes\Malwarebytes' Anti-Malware\Logs

Step 2 -- Run DDS and create 2 logs:

Download DDS from one of the locations below and save it to your Desktop:

Temporarily disable any script blocker if your Anti-Virus/Anti-Malware has it.
How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

Once it is downloaded, you can disconnect from the Internet and disable your Ant-Virus temporarily if needed.
Then double click dds.scr or dds.com to run the tool.
Click the Run button if prompted with an Open File - Security Warning dialog box.
A black DOS console should open and run for a moment.

  • When done, DDS will open two (2) logs:
    • DDS.txt
    • Attach.txt
  • Save both reports to your desktop
  • Please attach both of the following logs to your next reply: DDS.txt and Attach.txt
    --->You can ignore the note about zipping the Attach.txt file in most cases.

Yeah I agree the more important scan is the quick scan as it detects anything actively running.  Still running a full scan, from time-to-time, is useful.


I did check out that page.  However as stated I have performed a hardware check against the h.d.d. and filesystem (NTFS).  This system runs Diskeeper Pro which defrags daily automatically.  I will say I haven't run MB in safe-mode but thought about it.  However I know it is best to not run MB in safe mode and since quick scan in normal mode works I haven't care to try that approach.


It seems MB is having trouble with some file but since the program crashes and takes out the GUI I can't get the error message.  If I attempt to load another program like Notepad I will get a .dll error which goes away once the system is rebooted.  Still as stated SecureAnywhere scans all files with zero issues so between that and CHKDSK the filesystem and h.d.d. seem in good shape.


If only quick scan will work so be it that is the most important.  I still have SecureAnywhere to do full file scans from time-to-time.  I just thought I would see if there where any suggestions.  This system is old but is still rock solid and until MS EOL's Windows XP I will keep this workstation in use.

Gotcha. :)

Thanks for the update.


Yes, the suggestion is to run both of those tools and post back here with the logs. :)

It will only take a few minutes.

Without them, it's hard for anyone -- even the expert staff members -- to say what might be happening.


Are you running MBAM Free or PRO?

>>>If PRO, do you have mutual exclusions between WSA and MBAM?


If you are a paid user of PRO and prefer help via the help desk, please open a ticket with them by filling out the form >>HERE<<.

They will contact you directly for one-on-one help via email.

Either way, someone will need to see some basic diagnostic logs in order to help sort this out. ;)
