Following Google’s lead, Yahoo is moving to make its search engine safer.

Yahoo and McAfee on Tuesday announced a partnership to integrate McAfee’s SiteAdvisor technology with Yahoo Search. SiteAdvisor tracks Web site security issues, identifying sites associated with adware, malware, spyware, phishing, and spam.

The new SearchScan feature in Yahoo Search is a manifestation of the partnership. It provides red warning messages about the risks posed by Web sites that appear in Yahoo Search results lists.
