Windows 7: BSOD windows 7 when using browsers

BSOD windows 7 when using browsers

I have gotten several BSOD in the last month and most point to a bad driver. I have loaded WDK and have several mini-dumps and memory dumps. I have also installed Driver verifier. The majority of the dumps have Bad_Pool_Header as the cause of the crash. I have set up my machine to use Special pools and the last dump was DRIVER_PAGE_FAULT_IN_FREED_SPECIAL_POOL STOP: 0x000000d5 with "Caused by driver" ntoskrnl.exe although Wfpent8.sys showing up in several dumps too.

Hi fival01,

Welcome to the 7forums

Please lookup the details of the driver you mentioned, wfpent8.sys, located in %systemroot%\system32\drivers\

Please remove McAfee and replace it with Microsoft Security Essentials.
Please check Dell for driver updates for the USB drivers, it is possible that they are included in the chipset drivers.
Please remove all USB devices from your laptop.

Not possible to remove Mcafee due to it is an enterprise solution in my office and I do not control McAfee.
I cannot find the vendor for wfpent8.sys. It just says unknown. If I stop it, it crashes and I have to do system restore.
It is hard to remove USB devices because it is a laptop and the mouse is a touch pad

Could you repair/reinstall McAfee?

No problem, then just update the drivers

What do you mean with 'stop it'? A driver can't be stopped unless you delete it.

I am attaching the picture of how I "stop" it under Device Manager" > "View" > "Devices by connection" > "Show hidden devices"

As you probably now, that is a list of all real/emulated devices, when a crash occurs when disabling either of them means it is vital to software or a device.
Unfortunately if the details in device manager are the same as when you look it up via explorer then it'll be difficult to find what it belongs to if it isn't malware or something. Why I say 'malware' is because the search results aren't giving proper results about it, the only thing I know of that can have such results is malware.
