What is the Killer Network Service?

Killer Network cards are an Intel series of WiFi cards focused on gaming. They’re most commonly seen in gaming laptops and provide as low latency as possible when gaming over WiFi networks.

However, they require additional software such as the Intel Killer Control Center or the Killer Network Service to run properly. This might end up hogging system resources and leaving your computer unresponsive. 

Is it a virus?

In most cases, the service is entirely legitimate and safe to run. Yes, it might occasionally show a spike in CPU resources, but that’s about all the effect you’ll see. However, malware operators have been known to use malware resembling a Windows’ service name; if the service on your PC is using PC resources for a sustained period, there’s a possibility that it’s a virus.

The genuine service is installed in C:\Program Files\KillerNetworking\KillerControlCenter. If the program you’re dealing with isn’t in this location, it could be a virus or malware.
