New SearchScan Feature from Yahoo! Search Warns Users About Dangerous Sites Before They Click on Them

SUNNYVALE, Calif. & SANTA CLARA, Calif., May 06, 2008 (BUSINESS WIRE) -- Yahoo!, Inc. (Nasdaq:YHOO) and McAfee, Inc. (NYSE:MFE) today
announced a partnership to deliver a safer Web search experience
through Yahoo! Search. Launching in beta today, the new SearchScan
feature by Yahoo! Search, powered by the award-winning McAfee(R)
SiteAdvisor(R) technology, provides always-on alerts to users for
"risky" sites with security concerns such as spyware, adware and other
malicious software that can infect and damage a user's PC. SearchScan
also identifies sites that have shown bad email practices, flooding
user in-boxes with spammy emails. SearchScan is available for Yahoo!
Search users in the US, Canada, UK, France, Italy, Germany, Australia,
New Zealand and Spain. The McAfee Yahoo! partnership is a multi-year,
global agreement with additional elements, including bringing Yahoo!
Search to McAfee users, in the next few months.

By integrating McAfee's technology into Yahoo! Search, sites that
may harm the user's computer just by visiting them will be eliminated
from appearing in Yahoo! Search results. SearchScan also alerts users
to potentially risky sites with a red warning sign in search results,
allowing users to proceed with caution. During this beta period,
SearchScan displays McAfee alerts optimal for the Yahoo! Search user
and does not include all McAfee SiteAdvisor red ratings. (See Diagram

After children's safety, 65 percent of Americans online are more
worried about clicking unsecured search listings than the threat of
neighborhood crime, getting ones wallet stolen or email scams.*
SearchScan addresses users urgent need to avoid visiting dangerous
sites on the Web when conducting a search. The McAfee Yahoo!
partnership represents a major step forward for safer searching
online; users who conduct Web searches with Yahoo! will be warned
about the many malicious and dangerous Web sites before they visit
them.

"The new SearchScan feature from Yahoo! Search makes searching the
Web even safer than ever before. No other search engine today offers
this level of warning before visiting sites that can damage or infect
a user's PC and cost them valuable time and money," said Vish
Makhijani, senior vice president and general manager of Yahoo! Search.
"Through this partnership with McAfee, we can offer users a safer
search experience and drive more users to make Yahoo! Search their
starting point on the Web."

"We are very excited to have Yahoo! as a partner to make the
Internet more secure for everyone," said Tim Dowling, McAfee vice
president, Web Security Group "The advance warning offered by McAfee
SiteAdvisor is one of the strongest weapons in the battle against
online threats. Research indicates that 4 out of 5 Web site visits
start with a search, and consumers who use Yahoo! Search will now be
alerted to high-risk Web sites. This protects users from known
malicious threats such as browser exploits that will wreck their PC
with a single click or spyware that can lead to identity theft."
