Laptop freezes and static screen appears when doing malwarebytes scan

Recommended Posts

I have used malwarebytes numerous times on my windows 7 toshiba laptop and this never occured before.

I was scanning my laptop with malwarebytes and about 60 minutes in my laptop froze and had a static screen similar to this https://i.ytimg.com/vi/24sRyZmhuX8/maxresdefault.jpg

I had to force shut down my laptop.

Then when I turned on my laptop I did another malwarebytes scan and within a few minutes the static screen came up again and I had to shut down my laptop

Let's try and get some logs first so the team can review them and see if they can tell what may be causing your issues....

  1. FIRST: Create and obtain Farbar Recovery Scan Tool (FRST) logs Tell any program that blocks it to ignore or allow. It IS SAFE.
  2. Download FRST and save it to your desktop
    NOTE: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit
  3. Double-click to run FRST and when the tool opens click "Yes" to the disclaimer
  4. Press the "Scan" button
  5. This will produce two files in the same location (directory) as FRST: FRST.txt and Addition.txt
    NOTE: These two files will be collected by the MB-Check Tool and added to the zip file for you
  6. NEXT: Create and obtain an mb-check log
  7. Download MB-Check and save to your desktop
  8. Double-click to run MB-Check and within a few second the command window will open, then click "OK"
  9. This will produce one log file on your desktop: mb-check-results.zip
  10. Attach this file to your forum post by clicking on the "Drag files here to attach, or choose files..." or simply drag the file to the attachment area

The appearance of that screen seems to indicate a hardware problem with your graphics card/GPU.  It's probably being brought on by heat as the system is pushed during the Malwarebytes scans.  Go ahead and follow the instructions above, however I'd also suggest perhaps doing some hardware diagnostics as well to determine if a hardware issue is not the cause.

Thinking the same thing, Most likely running custom scan instead of the recommended threat scan. 

Possibly, but even the default Threat scan still taxes a system pretty hard, especially with the new (since 3.x) multi-threaded scan engine.  It gets pretty intense, so much so that I actually use it as a way of measuring and testing the overclock settings on my CPU/motherboard (shoot for the shortest scan time with temps still stable and no crashes/BSODs).

Threat scans do not usually take that long.;)

Right you are.  I missed that part about the scan time.  That definitely makes it sound even more like a heat related hardware issue.  Probably time for a data backup too just to be on the safe side as heat can wreak havoc on pretty much all forms of hardware, including storage devices.
