Chip maker Intel says it has agreed to buy computer-security software maker McAfee Inc. for $7.68 billion, or $48 per share. Intel Corp., which is based in Santa Clara, Calif., said the deal highlights “that security is now a fundamental component of online computing.”

The per-share price represents a 60 percent premium over McAfee’s Wednesday close of $29.93. Shares surged 58 percent after the deal was announced Thursday to hit $47.42.

Both boards of directors have unanimously approved the deal. The deal still requires McAfee shareholder approval and regulatory clearances.

McAfee is also based in Santa Clara.
