People will click on anything.
That was evidenced by the 409 people who clicked on an ad that offers infection for those with virus-free PCs. The ad, run by a person who identifies himself as security professional Didier Stevens, reads like this:
Is your PC virus-free?
Get it infected here!
Stevens, who says he works for Contraste Europe, a branch of the IT consultancy The Contraste Group, has been running his Google Adwords campaign for six months now and has received 409 hits. Stevens has done similar research in the past, such as finding out how easy it is to land on a drive-by download site when doing a Google search.
Of the 409 people who clicked, 98 percent were running Windows machines, according to the user agent string, which is a text string that identifies a Web site visitor to a server.
