A clip of Britain's Got Talent finalist Susan Boyle is the most watched video on YouTube.

According to YouTube's parent, Google, Scottish singer Susan Boyle's appearance on Britain's Got Talent was watched more than 120 million times on the company's servers.

Boyle was ahead of 'David after dentist' with more than 37 million views, and the 'JK wedding dance' on around 33 million views. These are figures for the whole world, not just the the UK.

In terms of global search terms for Google, 'Susan Boyle' was top in April 2009, a year in which other top search terms included 'Michael Jackson', 'Christian Bale' (in response to a notorious set outburst), 'paranormal activity', 'Tiger Woods', and the 'inauguration of President Obama'.

What the list tells us is that people's search and viewing interests go beyond the assumed ones of celebrities and obvious world events. If a little boy can be entertaining enough after a dental trip, he too can be up there with the rich and famous.

What doesn't feature on the list is how all of this viewing and searching of the world's leading search company is exploited by criminals to lure people into social engineering attacks and cons.

A good example from the last 24 hours is the first test flight of the Boeing 787 airliner, the Google video searches for which were infested with rogue links to malware within minutes of the event itself, according to security company, eSoft.

"While the distribution points and payloads varied, their effectiveness did not. Most sites were undetected by Google Safe Browsing and the malicious payloads they delivered had very low anti-virus detection rates," said the company in a blog.
