Two Texas men have been accused of earning more than $500,000 by selling pirated copies of various Adobe software products, including several program bundles to federal agents in Fairfax, court documents filed in Alexandria’s federal court said.

Robert D. Cook financed the operation and his son Todd A. Cook operated the three Web sites they used to sell the stolen software, an indictment unsealed last week said. Authorities say they sold more than 5,000 unauthorized copyrighted Adobe programs on their three Web sites: bargainsoftwaredownload.com, econo-soft.com and esoftdirect.com. They were arrested Tuesday on copyright infringement charges. Calls to their attorney, Donald Morris, were not returned.
