I downloaded this program from the official site and AVG antivirus gave me a warning that the software contained a trojan horse, due to how password crackers work it is possible your antivirus will trigger a security warning too, it is up to you to decide what to do, I also got a popup warning from Cain&Abel saying that I had Windows firewall enabled and this would stop some features, implying that I should disable it for everything to work. You will be asked to optionally install WinPCap a packet capture library, without it Cain&Abel wireless packet sniffing won’t work.
