It turns out that Canadian popstar Avril Lavigne is not just potentially dead, she's also the most dangerous person on the internet.
Cybersecurity firm McAfee has said the Sk8er Boi songster was the celebrity most likely to direct internet users to websites that carry viruses or malware.
Almost 15 percent of searches involving Lavigne led to websites that may contain potentially harmful malware. That number jumps to 22 percent if you search for an illegal version of her songs.

After Avril came Bruno Mars, Carly Rae Jepsen, Zayn Malik, Céline Dion, Calvin Harris, Justin Bieber, Sean 'Diddy' Combs, Katy Perry and Beyoncé.
If you're wondering what I meant when I described her as 'potentially dead', well the 32-year-old has been subject to a lot of a speculation by online crackpots.
The theory is that she died way back in 2003 and the Avril we have seen and heard since then is a body-double and paparazzi decoy named Melissa Vandella.
Subscribers to this theory think it explains why Avril's music and look changed so much between the start of her career and now.
A Twitter theorist claims the Canadian pop star didn't cope very well with fame, so she hired a lookalike to pose for paparazzi etc. That lookalike was Melissa.
The two became friends and, one night in the studio, Avril thought it would be a laugh to teach Melissa how to sing like her. Is that a thing? Can you teach someone to sing like someone else? I'm not sure about that, but let's not start picking holes in this.
Fast-forward to 2003 and, the theory goes, Avril took her own life after the death of her grandfather.
Rather than let the star's family grieve in peace, her record label decided to use the lookalike to continue with the pop-success Avril had experienced.
Either way, she's also the most dangerous woman on the internet to boot.
