Ever since the upgrade I have not been able to use my computer. I'm stuck in this loop. There's an issue with mcafee antivirus from what the code says. How do I get out of this? Someone please help! Mfewfpk.sys is the error not less or equal to.

You can try the following but it may or may not solve the problem. You will first need to change your UEFI/BIOS settings to disable SecureBoot and also Quickboot/Fastboot if those options are also in settings and enabled.


Download FatDog64 here. Fatdog64-701.iso  Burn the iso file on a Windows 7 or 8 computer to CD by Right clicking the downloaded iso file and selecting Burn Disk Image.


You can also create a bootable USB flashdrive using Rufus. If you do this try MBR partition scheme first. If that fails then use GPT. Where you see FreeDos in the dropdown box select iso image, click the folder icon and browse to the Fatdog iso file. Press Start. Backup any data on the USB flash drive as it will be formated.


Boot to the FatDog desktop. Some computer have a boot menu you can access at boot to select your boot device. Place the Disk in the optical drive or attach the USB flash drive and press the boot menu key to select the USB or CD. You may have to change your Boot order in UEFI/BIOS.


Your hard drive partitions will be located in the lower left of the desktop labeled sda1...sda2...depending on the number of partitions you have. It could be quite a few on a WIndows 10 upgrade. Click once on one of the sdaX icons. It may be sda2 or any of the others. A file Manager Window will open. If you do not see your Windows folder, close the File Manager and try another icon. When you find the sdaX icon with the Windows folder click once on the Windows folder to open. With Fatdog you only need to click once to open a folder. Then click once on System32 > drivers. In the drivers folder look for Mfewfpk.sys which is the Mcafee firewall driver. Right click the file and select Rename. Change it to Mfewfpk.bak


Exit out of Fatdog and reboot. Hopefully Windows 10 will not BSOD and boot normally.
