Shares of McAfee jumped 14% Friday after the security software maker blew past analysts' estimates.

McAfee's sales to consumers more than doubled in the first quarter, driving the company's earnings to 27 cents a share, 8 cents better than analysts expected. Overall revenues climbed 7.8% to $236 million, nearly $20 million better than forecast.

The company also raised full-year guidance on expectations that strong security spending will continue. The company expects full-year earnings of $1.15-$1.20 a share on sales of $955-$975 million.

McAfee's results followed a strong report from Symantec earlier in the week.
