What happened to John McAfee?
McAfee was found dead in his cell at Brians 2 prison near Barcelona on 23 June 2021 — the same day a Spanish court approved his extradition to the United States, according to Reuters. Prison workers discovered him hanging from his cell around 6 p.m., as reported by El País. Medics tried to resuscitate him but were unsuccessful, the BBC confirmed.
How did John McAfee die?
Spanish authorities ruled the death a suicide. A later ruling in 2023 from a Spanish court concluded “there is no indication of anything other than suicide,” El País reported. The Catalan justice department stated medics attempted resuscitation but could not revive him, per BBC.
Where did John McAfee die?
He died at Brians 2 prison, a penitentiary facility near Barcelona, Spain. He had been held there awaiting extradition to the U.S. on federal tax evasion charges, Wired confirmed.
The implication: The official ruling closed the case, but his widow continues to challenge the narrative.
McAfee’s widow, Janice McAfee, insisted he was not suicidal and asked for a full investigation. The Spanish court’s 2023 ruling closed that door definitively.
The catch: The legal system has spoken, but the public debate over his final hours persists.
Why was John McAfee jailed?
McAfee faced a 2020 federal indictment in the United States for tax evasion and failure to file tax returns, Wired reported. He was also a person of interest in the 2012 murder of his neighbor, Gregory Faull, in Belize.
What was the McAfee scandal?
Beyond the tax charges, McAfee’s life was marked by a pattern of flight. After the 2012 murder, he fled Belize and was briefly arrested in Guatemala. In 2019, he was arrested in the Dominican Republic on weapons charges. By 2020, he was living in Spain when U.S. authorities indicted him, leading to his arrest there.
What charges did John McAfee face?
- Tax evasion (federal indictment, 2020) — alleged he failed to file returns and concealed assets
- Person of interest in the 2012 murder of Gregory Faull (no charges filed)
- Weapons charges (Dominican Republic, 2019)
The pattern: Legal limbo became his permanent state as he moved from one jurisdiction to another.
The 2012 murder investigation in Belize was never resolved. McAfee’s flight from that case, combined with later indictments, meant he spent the last years of his life in legal limbo.
The implication: The unresolved murder shadowed every subsequent legal move.
Was John McAfee ever a billionaire?
McAfee was never a billionaire. His peak net worth was estimated around $100 million, which he made when he sold his stake in McAfee Associates in 1992, Reuters noted. His fortune dwindled due to poor investments, legal fees, and a lavish lifestyle.
What was John McAfee’s peak net worth?
At the time of the McAfee Associates sale, he walked away with an estimated $100 million. That figure — widely cited by multiple outlets including The Mirror and Daily Star — represents his peak wealth. He never approached the billionaire threshold.
What happened to John McAfee’s fortune?
By the time of his death, his net worth had reportedly fallen to about $4 million, according to The National. Business losses, real-estate ventures that failed, and the cost of his legal defenses consumed most of the original $100 million.
McAfee cashed out of his own company early — the classic founder’s dilemma. He got $100 million, but he lost the future value that Intel later paid $7.7 billion for in 2011.
The consequence: A fortune that could have been hundreds of millions evaporated through poor decisions and legal costs.
Why does no one like McAfee?
McAfee’s reputation suffered on two fronts: his personal behavior and the product that bore his name. He cultivated an erratic public persona — drug use, multiple marriages, run-ins with law enforcement — while the McAfee antivirus software itself became widely disliked for intrusive updates and difficulty to remove.
Was John McAfee a genius?
McAfee was a competent programmer who worked briefly at NASA and built early antivirus software. But he was not a technical genius in the way his myth sometimes suggested. His real skill was in marketing and self-promotion, and in riding the early internet security wave.
What controversies surrounded John McAfee?
- 2012 neighbor murder investigation in Belize
- Multiple marriages (5 total) with allegations of violence
- Drug use — he openly discussed his cocaine and marijuana use
- Fugitive lifestyle — fled from Belize to Guatemala to Dominican Republic to Spain
The pattern: A combination of personal scandal and product annoyance ensured his reputation was permanently damaged.
Did Janice McAfee get his money?
Janice McAfee, his fifth wife whom he married in 2013, claimed to have inherited his estate. But reports indicate he left little money — estimates of his net worth at death hover around $4 million, and legal fees had eroded most of what remained.
Who was John McAfee’s wife?
Janice McAfee (née Dyson) was his fifth and final wife. She was 31 years his junior and stood by him through his legal battles, speaking publicly after his death to dispute the suicide ruling and ask for an investigation, per Reuters.
How many times was John McAfee married?
Five times. His marriages included relationships with women in Belize and the U.S., with Janice being his final wife.
Did John McAfee have any children?
Yes — two children from previous relationships. They were not publicly involved in his later legal battles or his estate.
Janice McAfee inherited an estate that was largely drained by legal fees. The fortune he made from antivirus software was mostly gone by the time he died.
The consequence: The widow inherited little more than legal battles and a contested narrative.
Does John McAfee still own McAfee?
No. John McAfee sold his stake in McAfee Associates in 1992 and had no involvement with the company after that. The company that still bears his name has been through multiple ownership changes.
Who owns McAfee antivirus now?
McAfee (the company) was acquired by Intel in 2011 for $7.7 billion. Intel later spun it off, and it became an independent publicly traded company again. The product is now owned by a consortium of investors including Advent International and Permira.
When did John McAfee sell McAfee?
1992 — the year he cashed out for $100 million. He never worked on the product again, though his name remained on the packaging for decades.
The irony: The product that made him famous outlived his involvement by decades.

Quotes from key voices
“I am contented here. I have friends. The food is good. All is well. Know that if I hang myself, as Epstein, it will be no fault of mine.”
— John McAfee, from his blog, posted months before his death
“He was not suicidal. I want a full investigation into the circumstances of his death.”
— Janice McAfee, widow, statement to Reuters
“McAfee was a pioneer in the antivirus industry, but his life off-screen was a tragicomedy of excess and paranoia.”
— The Guardian (editorial obituary)
The implication for anyone following the story: McAfee’s own words — a claim that he was not suicidal — directly contradicted the official finding. His widow continues to insist there was more to the story, but Spanish courts have closed the case.

For anyone tracking the pattern of high-wealth founders who lost everything in legal battles, the lesson is blunt: a $100 million fortune can evaporate if legal fees, bad investments, and a fugitive lifestyle consume it all. For John McAfee, the cost of his freedom — and his life — was the entire fortune he built.
