Manually clear npf virus killing method

Virus killing has a variety of ways, let us introduce the manual killing method. Npf.sys (%system32/drivers/npf.sys) is the main file of the npf virus, virus modification registry creation system service NPF implementation self-starting, running ARP spoofing, when the virus machine forges MAC address, keeps on to each machine Sending an ARP packet blocks the network, making the data slower and slower, and allowing the user to log back in to the game by pseudo-dropping, so that it can intercept the information data when all users in the local area log in to the game.
The virus often causes network congestion, causing a blue screen on the machine when it is serious!!!! Start anti-virus:
1. First delete the npf.sys file under %system32/drivers/
2. Enter the registry to delete the
HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Npf service.
Also delete
HKEY_LOCAL_MACHINE/SYSTEM/ControlSet001/Enum/Root/LEGACY-NPF
HKEY_LOCAL_MACHINE/SYSTEM/ControlSet002/Enum/Root/LEGACY-NPF
3. When deleting these two keys, you will be prompted Can not delete, right click, permissions, set everyone control, delete.
npf virus is a common type of virus in computers. Through the above explanation, I hope everyone has mastered this method.
