Summary

Backdoor:Win32/Cycbot.G is a backdoor trojan that allows attackers unauthorized access and control of an affected computer. After a computer is infected, the trojan connects to a specific IRC server and joins a specific channel to receive commands from attackers. Commands can instruct the trojan to spread to other computers by scanning for network shares with weak passwords, exploiting Windows vulnerabilities, or possibly spreading through backdoor ports opened by other families of malicious software. The trojan may also allow attackers to perform other backdoor functions, such as launching denial of service (DoS) attacks and retrieving system information from infected computers.
To detect and remove this threat and other malicious software that may have been installed in your computer, run a full-system scan with an up-to-date antivirus product such as the following: For more information about using antivirus software, see http://www.microsoft.com/windows/antivirus-partners/.
