Research by McAfee’s SiteAdvisor suggests that the spread of malware and viruses is linked to search engine usage. The research is based on an analysis of thousands of search query results pages from the industrys leading engines. The results often link to websites that could damage users computers or subject them to spam e-mails. Google says it doesnt employ advertisements associated with malware or viruses, and it removes any it finds that link to risky sites. Microsoft also says it offers tools and features to help consumers combat malware.”]
