5. Enrique Salem, President and CEO, Symantec
No other company can match the big gains Symantec has made this year in both sales and operations. That's due in large part to Symantec President and CEO Enrique Salem. If Symantec Chairman John W. Thompson had the chutzpah to build a bigger Symantec, then Salem had the management hand to pull it all together. He's the right executive for the right time. With only eight months under his belt as CEO, look for Salem to lead Symantec to even greater heights in 2010.
