Superhero fans looking to learn more about their favorite characters online might run into security risks that even Superman can’t detect.

Search engine users who searched for “Superman,” “Superman and free torrent download,” “Superman and watch,” “Superman and free app,” and “Superman and online,” have a 16.5 percent chance of finding a website containing online threats, which could include spyware, adware, spam, phishing, viruses and other malware, according to a new McAfee study.

McAfee looked at which superhero searches led to the highest chance of a user being exposed to some kind of cyber risk.

In second place on the company’s ‘Most Toxic Superheroes’ list was Thor at 16.35 percent, while Wonder Woman and Aquaman tied for the third place slot at 15.7 percent.
