The study used 'McAfee SiteAdvisor' site ratings, which indicate which sites are risky to search for celebrity names on the Web and calculate an overall risk percentage.

'Mr Fantastic' was found the second most vulnerable superhero with 18.22 per cent of chances of landing on a website exposed to online threats, such as spyware, adware, spam, phishing, viruses and other malware.

The Hulk (17.30 per cent), Wonder Woman (16.77 per cent) and Daredevil (16.70 per cent) are among the top five superheroes leading to infected content online.

On steps to protect from online threats, McAfee said that free downloads are significantly the highest virus-prone search terms. "Anyone searching for videos or files to download should be careful as not to unleash malware on their computer," it said.

Security technology company McAfee is a wholly-owned subsidiary of world's largest computer chip maker Intel Corporation.
