McAfee + Yahoo = Secure Search

McAfee Inc and Yahoo Inc are joining hands to offer alerts about unsafe and dangerous websites while displaying search results at yahoo.com.

With this new security feature, which is expected to come into effect by May 6, people who search the internet using Yahoo will see a red exclamation mark and a warning next to links that McAfee has identified as serving dangerous downloads or using visitors' e-mail addresses to send out spam.
Dangerous downloads can include "adware," which shows unwanted advertisements; "spyware," which secretly tracks users' keystrokes and other actions; and other malicious programs that can give criminals control over users' computers.If McAfee has identified a site as having employed such tactics, Yahoo users won't see the link at all.
After Google, Yahoo operates the second most popular search engine among U.S. users, with 21 per cent market share compared to Google's nearly 60 per cent, according to data for March, the latest available, from ComScore Inc.
McAfee also benefits from teaming with Yahoo because it can use Yahoo's search data to identify sites to examine for security holes and include within its products.
I tried using Yahoo search today but couldn't locate any such red exclamation sign.
