* Anteon International of Fairfax more than doubled its profit in the third quarter, largely as a result of a boost in government spending on information technology. The firm reported net income of $8.2 million (22 cents per share), up from $3.4 million (13 cents) in the year-earlier period. Revenue jumped about 17 percent, to $214.3 million from $183.7 million. The increase was largely related to a surge in orders from the Defense Department and the intelligence community, which make up 90 percent of the company's revenue. The nearly $400 billion defense budget recently signed by President Bush and the proposed Department of Homeland Security will continue boosting revenue, which should grow 13 to 15 percent in 2003, company officials said. Shares of Anteon fell $3.76, to $23.
