Lex Luthor isn't the only person who should be afraid of Superman.

A new survey by anti-virus software company McAffee reveals Superman is the most toxic superhero to search for online.

They say searches for the Man of Steel have the biggest likelihood of bad links -- including viruses, malware and phishing scams that steal passwords and personal information. 

Wonder Woman and Aquaman tied for third, with Wolverine, Spiderman, Batman, Black Widow, Captain America, Green Lantern, and Ghost Rider completing the Top 10.
