This is the software publisher's description.

Malicious software called Bots can secretly take control of computers and make them participate in networks called “Botnets.” These networks can harness massive computing power and Internet bandwidth to relay spam, attack web servers, infect more computers, and perform other illicit activities.

Security experts believe that millions of computers have already joined Botnets without the knowledge of their owners. By using remotely-controlled computers, the criminals in charge of the Botnets try to remain anonymous and elude authorities seeking to prosecute them.

RUBotted monitors your computer for suspicious activities and regularly checks with an online service to identify behavior associated with Bots. Upon discovering a potential infection, RUBotted prompts you to scan and clean your computer.
