Creator of McAfee security software and its namesake, John McAfee, has been found dead in his Spanish prison cell.

According to the Catalan Justice Department (via BBC) signs indicate that McAfee took his own life. He was 75.

Back in October, McAfee was arrested in Spain on a US indictment. The entrepreneur was accused of failing to file tax returns for four years and concealing assets including a yacht and real estate.

On Wednesday, hours before his apparent suicide, Spain’s National Court approved McAfee’s extradition to the US to face the above charges.

The life of John McAfee has been interesting and for many he was a controversial figure.

While McAfee’s creation earned him a lot of money, even he was aware that McAfee software had become synonymous with bloatware.

When Intel purchased McAfee Security in 2010 and decided to change the name to Intel Security, McAfee said “I am now everlastingly grateful to Intel for freeing me from this terrible association with the worst software on the planet.”

The controversy in McAfee’s life started after he moved to Belize in 2008. With his fortune dwindling and a series of failed investments McAfee became the focus of an investigation into the death of his neighbour.

At this point McAfee sought asylum in Guatemala in 2012 only to be expelled.

In recent years McAfee has tried to run for President of the US and participated in numerous cryptocurrency ventures.
