Gettng Blue Screen stop errors: 0x000000E1 (0x83826535, , 0x85fc3818, 0x85FC3818)

i have no idea on how to fix this error, i've been getting these more often lately. So often that whenever i log it shows these BSOD and WORKER_THREAD_RETURNED_AT_BAD_IRQL, the Laptop is a compaq with productId: WL707LA#AC4 with only 2gb of RAM. I added the product if you needed the tech specs of the laptop. Also i havent installed new components or drivers nor new software. Can anybody please help?

The driver that appears to be the problem is the mfewfpk.sys:

The mfewfpk.sys is a McAfee firewall driver and the problem you are experiencing is similar to that reported in the following thread:

As in that thread there also appears to be Microsoft Security Essentials installed on your system so I would suggest to uninstall McAfee and Microsoft Security Essentials and then install a fresh copy of either Microsoft Security Essentials or McAfee but not both.

Also since McAfee and/or Microsoft Security Essentials may not have been working properly consider running a scan with the following two applications just to see if they pick anything up:
