An Annandale man pleaded guilty Thursday to copyright infringement for selling more than $2.3 million in counterfeit computer software.

Quynh Trong Nguyen, 36, allegedly sold the copyright-infringing computer software for more than three years, according to a press release from the United States Attorney’s office for the Eastern District of Virginia.

Nguyen has also agreed to forfeit more than $650,000 in seized liquid assets, the release said.

Court documents related to the case say Nguyen sold software such as Adobe Acrobat and Microsoft Office through Internet websites he created in his Annandale home. The software was acquired from overseas. The release states that an estimated 2,000 customers were defrauded.

Nguyen was also accused of falsely representing himself as buyer and seller of educational software in connection with George Mason University. According to the release, Nguyen “then altered the educational software, which he later sold at higher prices, by painting over labels and modifying the product packaging.”

The case was investigated by Homeland Security Investigations and the United States Postal Inspection Service.
