BSOD while surfing web: Error 0x0000000019 BAD_POOL_HEADER

Hey everyone,
I first want to say Thank you for this community, you guys are a great help throughout my life. This is the first time I actually had to post for some help because this BSOD seem to have many different causes. Usually I could find the answer through the search option.

I just need some help, i just recently received a BSOD in class and lost all the notes i was taking in class. Frustrated, and sad, I am seeking for some help for this to never happen again. I rarely download anything on this laptop and use it for strictly school. I blame Sony laptops... but noneoftheless, can someone help me? Attached is the minidump. Thank you guys!

Welcome to the forum.

Please install service pack one: Learn how to install Windows 7 Service Pack 1 (SP1)

Looks like Malwarebytes is creating the BSOD's. If they persist after installing service pack one, then uninstall malwarebytes to test.
