Kwampirs is basically a backdoor trojan used by hackers to gain remote access to compromised computers. When executed, the Trojan decrypts and extracts a copy of its main DLL payload. Kwampirs target WMI performance adapter service present in windows and upon infection it makes the service as WMI Performance Adapter Extension (WmiApSrvEx) type autostart.It only targets windows system that doesn't any sort of security prevention mechanism such as the latest antivirus.It doesn't have anything to deal with Linux/Mac environment.
Check for the service WmiApSrvEx (WMI Performance Adapter Extension) if it is in running /stopped state means it is infected with kwampirs.
You can also check for the infection using the registry.
Key Path: CurrentControlSet\Services\WmiApSrvEx\
