Backdoor.IRC.Zcrew is a backdoor Trojan Horse that is similar to other backdoor IRC Trojans, such as Backdoor.IRC.Aladinz and Backdoor.IRC.Flood.
Backdoor.IRC.Zcrew is written as an IRC script and uses the mIRC client to connect to the Internet, where it notifies the attacker of its presence. The hacker can send various commands to an infected computer and take full control over it.
An infected computer can also be used to launch a ping flood attack against another computer at a specified IP address.
