The stock option backdating saga at McAfee, Inc., isn’t over. On Wednesday, former general counsel Kent Roberts sued the software maker for defamation. He claims McAfee made him the scapegoat for a federal probe into backdating at the company. Roberts says that as a result, he hasn’t been able to find another full-time job, even though he was acquited of criminal backdating charges last year.

The suit, filed in federal district court in San Francisco, says that officials at Santa Clara-based McAfee gave misleading information about Roberts to the U.S. Department of Justice and the Securities and Exchange Commission. Roberts says the aim was to divert investigators’ attention from the board of directors and former CEO George Samenuk. The campaign even had a name, according to the complaint: ‘Project Shield.’ Roberts is seeking unspecified damages.
