BOSTON, April 30 (Reuters) - McAfee Inc (MFE.N), the No. 2 security software maker, reported a stronger-than-expected quarterly profit, helped by new software modules and partnerships with PC vendors.

The company, which competes with No. 1 security software maker Symantec Corp (SYMC.O), forecast second quarter earnings at the high end of market expectations and its shares rose 3.4 percent in after-hours trading on Thursday.

McAfee's corporate sales rose after it added new modules to its portfolio, boosting the types of security software that customers purchase at once. Consumer sales are growing thanks to partnerships with PC makers, which preload McAfee's programs onto their machines.

"They've done a good job in scaling the model," said FBR Capital Markets analyst Daniel Ives. "This year, you are starting to see them reap the benefits."

McAfee posted a profit, excluding items, of 57 cents per share in the first quarter, beating the average analyst forecast of 48 cents, according to Reuters Estimates.
