Above the report from who crashed.

 

A few days ago I got a fake popup telling me my that my computer was infected, hit the OFF button and restarted the computer and everything seemed normal, I don't know if this is relevant to the next problem of BSOD, I just mention it to be complete.

After the first bad_pool_caller I totally uninstalled mbam and reinstalled, did a full scan, also a full scan with BitDefender, nothing was found and for a while the computer acted normally, until the next BSOD. I did a search and found out that BitDefender can also be the reason. Websites did not display properly in Chrome and Edge as well.

I uninstalled BitDefender and installed Kaspersky Internet Security and all seems OK, still I don't know if the problem will come back and what do I eventually have to do to prevent that error in the future.

Thanks in advance.

 

PS : I had to copy the full text since I still could not attach files

The memory dumps look similar to those that I've seen that are caused by a BitDefender driver.
Should the BSOD's come back, please provide the info from this link:  https://forums.malwarebytes.org/topic/170037-blue-screen-of-death-bsod-posting-instructions-windows-10-81-8-7-vista/

In the event that you can't upload files here, simply upload them to another file-hosting service (such as OneDrive or DropBox), ensure that they're shared, and then post a link to them here.

A bit more info:

The driver bdfwfpf.sys is the issue here (if BitDefender is still installed or if remnants remain.
It's important that it get updated (or removed if you've uninstalled BitDefender). 

Check for it in C:\Program Files\Common Files\Bitdefender\Bitdefender Firewall\bdfwfpf.sys
and see what version it is (AFAIK, the version 7.00.16 is the problem one).

@usasma : thanks for your reply, the file  bdfwfpf.sys is not on the computer any more.

Hopefully there is no next time but I will run the programs mentioned in your link referring to the posting instructions.

@TimBerlin : Thanks for your reply. I've got KIS running now and got rid of BitDefender.

Thank you, I really appreciate your help.
