Fake antivirus / scareware

Scareware is a real and well-documented form of cybercrime in which fake security alerts trick users into paying for worthless or malicious software. The FTC, FBI, and DOJ have all taken enforcement action against scareware operations.

What we know

Scareware programs display alarming but fabricated warnings claiming a computer is infected with viruses or malware. The goal is to frighten users into purchasing fake "security software" that either does nothing or installs actual malware. The FTC secured a $163 million judgment in 2012 against Innovative Marketing Inc., one of the largest scareware operations ever prosecuted in the United States.

The FBI's Internet Crime Complaint Center (IC3) issued warnings as early as 2009 that scareware had caused over $150 million in consumer losses. The DOJ also sentenced a payment processor who handled funds for a scareware cybercrime ring to 48 months in prison. These cases confirm that fake antivirus is not a myth but an active and prosecuted criminal enterprise.

Modern variants include tech support scam pop-ups that lock the browser and display fake Microsoft or Apple warnings, urging users to call a toll-free number. The FTC continues to receive thousands of reports of such scams annually. Users should only install antivirus software from recognized publishers obtained through official channels.
