  1. I got a BSOD ( . . . win32k.sys . . . begin physical memory dump . . . ) and looked to see what unsigned drivers I had. I think mbamchameleon.sys in this folder is related to Malwarebytes: C: \ Windows \ system32 \ drivers When I installed SplitCam, Win XP said that it could make the system unstable, but I installed it anyway, so I think that my BSOD was most likely due to splitcamaudio.sys But at this time, looking for any unsigned drivers, I also found mbamchameleon.sys in there . . . so I have removed it to a non-loadup folder (I think that's how this works) C: \ Windows \ system32 unsigned drivers I think the four unsigned lv's are for my Logitech camera, but I'm not sure, no concrete answers from googling, but I removed those also I just wanted to check here to verify that mbamchameleon.sys is Malwarebytes . . . I just ran Malwarebytes, and got no error message with mbamchameleon.sys moved. ************************************************************************************************************************************************************************************ To Verify Unsigned Device Drivers Start \ Run \ sigverif \ OK Advanced \ [dot] Look for other files that are not digitally signed \ Look in this folder: Windows \ system32 \ drivers Logging tab \ [check] Save the file signature verification results to a log file \ OK \ Start Advanced \ Logging tab \ View log You can move them from "system 32 \ drivers" to another folder you create (for backup purposes), ie: C: \ Windows \ system32 unsigned drivers Then Restart . . .
