Dangerous Searching

A new study by a unit of antivirus company McAfee finds that the major Internet search engines often send users to Websites that put them at risk of infection by spyware and other malicious software.

McAfee SiteAdvisor says Google, Yahoo, MSN, AOL and Ask.com do little to protect users from going to dangerous sites, and in fact make a lot of money by accepting ads that lead consumers to trouble.

The riskiest search terms include "free screensavers," "song lyrics," "singers," and "digital music."
