Wta:how To Prevent Netcut (arp Spoofing) With Bitdefender

a friend of mine give me program called netcut, it suppose to cut network access from target computer using arp spoofing, i'm curious so i try this program on my laptop, my current config as follow:

1. 1 PC server with internet connection, shared via AP on server (built in AP on PC)

2. my laptop, the program i run netcut

both PC using bitdefender internet security. with firewall activated and ICMP disabled

problem :

i execute netcut from laptop, then i try "cut" connection of other PC that currently connected to wifi

it works, but wifi connection also disconnected, and it happen to all computer connected to that same wifi network, wan connection in server PC not affected cause it use different network card.

i try reboot laptop, but wifi still disconnected

the only solution (at this time) is by restarting server

i also try to clear routing table, renew ipconfig on server

question:

is there someway defending PC from arp spoofing using bitdefender?
