There is one phrase which, if you type into any search engine will expose your PC to shed-loads of spam, according to a new report. Researchers Ben Edelman and Hannah Rosenbaum reckon that typing the phrase "Free Screensavers" into any search engine is the equivalent of lighting a blue touch paper and standing well back. More than 64 per cent of sites that are linked to this phrase will cause you some trouble, either with spyware or adware.

The writers of the report work for Site Advisor, recently acquired by AV firm McAfee, so might be said to have some self interest in all of this. I bet after reading that a lot of people will search for Free Screensavers LOL :)
