John McAfee, the founder of the antivirus software McAfee, has died by apparent suicide while awaiting extradition to the United States on tax-related criminal charges.

McAfee, 75, was found dead in a Barcelona jail cell on Wednesday, Spanish publications El Pais, citing police sources.

The Catalan justice department confirmed McAfee's death to Reuters.

Earlier in the day, Spain's National Court approved the extradition of McAfee to face the US-based charges.

McAfee, who made his fortune selling antivirus software, had been arrested at Barcelona's airport last October and held in jail while awaiting the outcome of the extradition hearings.

McAfee was accused of evading his taxes in Tennessee by failing to disclose money he made from cryptocurrency and speaking fees, as well as selling the rights to his life story for a documentary. McAfee was fighting the extradition.
