Fans of Lily Collins have been warned - the actress has been named the most dangerous celebrity to search for online. The British star, daughter of veteran rocker Phil Collins, has topped a new poll by officials at computer anti-virus firm McAfee, who found that searching for information about the Mirror Mirror beauty posed the biggest risk of landing a user on a malicious website. Singer Avril Lavigne took second place, while Oscar winner Sandra Bullock came in third. Others mentioned in the top 10 include comedienne Kathy Griffin and actress Zoe Saldana, while Mad Men's Jon Hamm was the only male to make the countdown. Harry Potter star Emma Watson was voted number one on the McAfee list last year (12).
