"Win32.Rbot.WO is an IRC controlled backdoor (or "bot") that can be used to gain unauthorized access to a victim's machine. It can also exhibit worm-like functionality by exploiting weak passwords on administrative shares and by exploiting many different software vulnerabilities, as well as backdoors created by other malware.
