Summary

Backdoor:Win32/Rbot.EJ is a backdoor Trojan that runs in the background, gathers software installation and computer configuration details, and connects to an IRC server to receive commands from remote attackers. Commands could include instructions to spread to other computers via open network shares or by exploit of a security vulnerability, or to launch a denial of service (DoS) attack against specified targets.
Backdoor:Win32/Rbot.EJ may download and install additional malicious software, thus manual removal is not recommended. To detect and remove this Trojan and other malicious software that may have been installed, run a full-system scan with an up-to-date antivirus product such as the Microsoft Safety Scanner (http://go.microsoft.com/fwlink/?LinkId=212742).
