Yahoo warns about dangerous websites

Yahoo attempts to make its search engine more secure with McAfee. SearchScan(made by McAfee SiteAdvisor technology) shows a red warning with search engine hits considered as malicious.

InformationWeek says that Google has added similar thing over a year ago but Yahoo says that their SearchScan is better than anyone currently
existing one.

It's not surprising that Yahoo and McAfee are working together as a year go Yahoo hits had greatest amount of dangerous links.
