Windows 7: BSOD after malwarebytes scan, BCcode 19 - Bad Pool Header

BSOD after malwarebytes scan, BCcode 19 - Bad Pool Header


Recently i installed MalwareBytes, and about 10-15 minutes after the scan i received an bsod. About 40 minutes after that i got another one, both of them with BCcode 19 - Bad Pool Header.

In the uploaded log collector you will see 3 bsod errors; the first one i got a few months ago while using an android emulator named BlueStacks (idiot me ignored the issue at the time because i saw a lot of people on their forums complaining about random bsods while using BlueStacks (there were some posts from tech staff who basically said "yeah, you get those every once in a while" - i uninstalled it after seeing this)).

The second dump is after i ran MalwareBytes, and the third is the one i got right ~40 minutes after the second one (my brother was playing Path of Exile if it's of any help).

Apart from buying a new keyboard (a Marvo K636) i didn't modified my hardware in anyway, and, from software pov, i only installed MalwareBytes yesterday.

Sorry for the bad english and thanks in advance for your time and help,

Was it the very latest version of Malwarebytes you installed?

Install a genuine version of Windows 7. Counterfeit installations are the cause of a lot of issues, and most BSOD analysts won't bother helping you unless the underlying system is genuine and error-free.

BSOD on wake from sleep, BCcode 19 - Bad Pool Header
This has been happening to me for awhile now. When my computer wakes from sleep, it will work perfectly fine for a little while until it seemingly randomly BSODs for no reason. This never happens if I don't put it into sleep. Here are the parameters: BCCode: 19 BCP1: 0000000000000020 ...
