If you are running version before 2.1.0, please upgrade by download the last version of netcut or netcut-defender

Please run netcut-defender if you only want to Protect youself from netcut.  Download here http://www.arcai.com/netcut-defender-faq.html

netcut itself has same function as netcut-defender, plus the power to CUT-OFF.

Note: Netcut must be "RunAs administrator" under windows 7, this is required as windows 7 only allow administrator to update the ARP cache.

How does it works (netcut-defender) ?

When you check "protect my PC",  netCut will ensure both Gateway and your own PC has the right ARP mapping.  this is only way to anti-netcut.

Netcut keep alive APR message will keep Gateway and your own PC aware of the correct mapping, the netcut will detect any spoofing packet, and response with correction action immediately.

If you are running a Xbox/Iphone/MAC or any other smart phone device, and want to ensure your PC can talk to those device, simple way is to set those device's IP as gateway, and select "protec my PC" inside netcut.

Cheers
