PICS: The world's most dangerous celebrities!

Web security company McAfee has released a list of 'most dangerous' celebrities to search for online -- we bring you the top 10.

McAfee, the web security company, has been releasing a list of the 'most dangerous' celebrities for the last few years -- German supermodel Heidi Klum topped the 2012 list and Emma Watson topped the year before last.

McAfee draws up this list based on the probability of landing 'on a page tested positive for spam, adware, spyware, viruses, or other malware' when you look for pictures of downloads of some of these famous people.

For instance there is a 9.8 per cent chance that you'll land on a spam site if you look for the Nancy Drew star Emma Roberts online.

Emma Roberts, who also happens to be the niece of actresses Julia Roberts and Lisa Roberts Gillan, is number ten on the list of the most dangerous celebrities online.

Brazilian Victoria's Secret Angel Adriana Lima is ninth in the list.

Adriana Lima was recently ranked by Forbes as the third richest model in the world with an annual earning of $6 million.

Lima has been a Victoria's Secret Angel since 2000 -- the longest any model has ever been -- and owes most of her income to the lingerie giant.

When she isn't being a mother-of-two and a devout Catholic, Lima endorses several brands including Donna Karan, Miu Miu and Metrocity among others.

According to McAfee there is a 9.9 per cent chance of you landing on a malware page if you look for images of Adriana Lima.

The Man Men star Jon Hamm may be known to many of us as the star who hung out with Priyanka Chopra when he was in Mumbai is number seven on the list.

Hamm, who is the only man in this list, has a risk percentage of 10.

Back with a bang and how! Britney Spears may be on the wrong side of the 30s but she's been packing a punch and how! We couldn't help being jealous of that toned bikini body she flaunted on this magazine cover and sweated under our collars when she showed up in this figure-hugging bandage dress for the premiere of Smurfs in late July...

Oh… just before you go looking for 'Britney Spears hot' on Google, it might be good to know that she's number seven on the list of the most dangerous celebrities online.

Now, besides the obvious one or two that occur to us, there are several reasons that we can imagine why you'd go looking for pictures of Katy Perry. But know that she's on number six in the list of the most dangerous celebrities online. There are, according to McAffee, 10.4 per cent chances you'll end up on a page you shouldn't if you look for her. Still want to go hunting? Try this!

She's been the face of Calvin Klein underwear… and for good reason. But Avatar actress Zoe Saldana has trouble written all over her as McAfee rates her above Katy Perry, Adriana Lima and Britney Spears at number five.

Zoe Saldana has a risk percentage of 10.5.

American actress Kathy Griffin was ranked number four in the list of the most dangerous celebrities by McAfee. According to the Internet security giant there are 10.6 per cent chances that you'll land on a troublesome page if you look for pictures or downloads of Kathy Griffin.

Sandra Bullock rounds up the top three in this dubious list with a risk percentage of 10.8… and we can completely see why!

The Canadian singer-songwriter Avril Lavigne spells trouble according to McAfee as she ends up second in the list of the most dangerous celebrities online with a risk percentage of 12.7. This should be of some concern because only months ago Zimbio.com rated Avril Lavigne as one of the top 20 most influential stars online.

English-American actress Lily Collins has topped the list of the most dangerous celebrity online.

Collins is the star of movies such as The Mortal Instruments: City of Bones and daughter of rock musician Phil Collins

"Lily quickly rose to fame as a talented actress, teenage journalist, and Hollywood trendsetter. She landed in the number-four spot in People magazine's 2012 World's Most Beautiful Women list and has the lead in The Mortal Instruments: City of Bones," McAfee writes of her on their website before announcing her as 'this year's most dangerous celebrity to search for on the web'.
