Superstar3.io is a deceptive search engine that is promoted through the use of malicious browser extensions and browser hijackers. When installed, these browser hijackers modify your web browser’s configuration to automatically send all searches through Superstar3.io. SuperStar.OptimizerService is a process associated with the Superstar3.io browser hijacker.
