Yahoo teams with McAfee to offer search results security

Technorati Profile
Yahoo Inc. and McAfee Inc. are joining to offer alerts about potentially dangerous Web sites alongside search results generated at Yahoo.com
With the new security feature - slated to take effect Tuesday - people who search the Internet using Yahoo will see a red exclamation point and a warning next to links 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.

Yahoo and McAfee hope the move will quell users' anxiety about accidentally clicking on malicious links.

"Yahoo users have clearly told us that among the most important concerns for them are all these lurking threats on the Internet," said Priyank Garg, director of product management for Yahoo's search division. "They know the damage they can do but they don't know how to protect themselves."

Yahoo has decided to simply nuke the worst offenders - sites that attempt "drive-by downloads," or trying to automatically install malicious code on visitors' computers by exploiting coding flaws in their Web browsers.

If McAfee has identified a site as having employed such tactics, Yahoo users won't see the link at all.

"When a user gets a set of search results, there's really no indication of who's a good guy and who's a bad guy," said Tim Dowling, vice president of McAfee's Web Security Group. "You're really leaping off a platform of faith that you're clicking on a site that's safe and not one that's bad. And the bad guys really try hard to look good."
