          Re: Registration Statement on Form S-8

Ladies and Gentlemen:

We have examined the Registration Statement on Form S-8 to be filed by you with the Securities and Exchange Commission on or about May 14, 2008 (the “Registration Statement”), in connection with the registration under the Securities Act of 1933, as amended, of 800,000 shares of Common Stock (the “Shares”) to be issued under the McAfee, Inc. Amended and Restated 1993 Stock Option Plan for Outside Directors, as amended (the “Outside Director Plan”).

As your legal counsel, we have examined the proceedings taken and are familiar with the proceedings proposed to be taken by you in connection with the sale and issuance of the Shares. It is our opinion that the Shares, when issued and sold in the manner referred to in the Outside Director Plan, and pursuant to the agreements which accompany the Outside Director Plan, will be legally and validly issued, fully paid and nonassessable.

We consent to the use of this opinion as an exhibit to the Registration Statement and further consent to the use of our name wherever appearing in the Registration Statement and any amendments thereto.

Sincerely,

WILSON SONSINI GOODRICH & ROSATI
Professional Corporation
