Fake Antivirus Scams on WhatsApp
Fraudsters send WhatsApp messages warning your device is infected, pushing you to install bogus 'antivirus' apps or pay for fake protection that delivers malware.
Part of: Fake Antivirus Scams
Last reviewed: 1 June 2026
A fake antivirus warning hits differently on WhatsApp, arriving among messages from people you trust. A note claiming your phone is infected, perhaps forwarded as if from a contact, borrows the credibility of the chat to push a malicious download or a payment.
Genuine security software does not diagnose your device through a WhatsApp message. The platform is useful to scammers because alarming forwards spread quickly between contacts, and a single tap on a shared link can lead to a fake 'antivirus' app or a payment page.
How this scam works on WhatsApp
The message warns that your device is infected or 'at risk' and urges you to install a recommended antivirus app or renew protection through a link. It may appear to come from a contact whose account was compromised.
The link leads to a fake security app that itself contains malware, or to a payment page charging for protection that does not exist. Once installed, the app can harvest data, display endless 'threat' alerts, or push further paid 'fixes'.
The urgency of an infection warning, amplified by arriving from a familiar chat, is designed to prompt a download before the victim questions it.

Frequently asked questions
Can a WhatsApp message really detect a virus on my phone?
No. A chat message cannot scan your device. Any WhatsApp warning that your phone is infected is a scam designed to make you install malware or pay for fake protection. Use only security apps from official stores.
