Tech companies make a game of naming their conference rooms. Some name the rooms for favorite beers, or superheroes, or nearby mountains and rivers. At McAfee's big new office in Hillsboro, the conference rooms are named for the company's enemies. Stuxnet, Mydoom, Nimda and CodeRed are among the most famous viruses to afflict computers. The Hillsboro site is one of the company's top threat research centers, responsible for finding new incarnations of viruses and developing technology to inoculate computers against them. One of the best-known names in online security, McAfee has had an Oregon presence for years. But the company sold to Intel for $7.7 billion in 2010, ceding its brand as Intel sought a way to integrate security software with its computer chips. Intel gave up last year, spinning McAfee back out as an independent, privately held business and restoring the original name. (Intel retained a 49 percent stake in the business.)
