Real malware warnings are rarely dramatic. The dramatic ones , red screens, sirens, countdowns, a phone number to call urgently , are almost always the scam itself. This page draws that theatrical version, which makes it useful as a joke and genuinely useful as a teaching example.
What it simulates
A scareware alert: a red warning field, an urgent sounding message about a detected threat, and the visual grammar of tech support fraud. Everything on it is decorative. There is no scan, no result and no threat.
A note on why these exist
The pattern this page imitates is the standard opening move of technical support fraud: a browser page fills the screen, claims an infection, and pushes the visitor towards calling a number or installing a “fix”. Two things are worth remembering when a real one appears.
- A web page cannot scan your computer. Anything in a browser claiming to have found a virus is guessing or lying , it has no access to your files.
- Legitimate security software does not ask you to phone anyone. Real antivirus tools alert you inside their own application, quietly, with no urgency and no phone number.
- The way out of a real one is to close the tab, or force quit the browser if it will not let you. Never call the number.
How to run it
- Press Start fullscreen.
- Press Esc or tap Exit to stop it , which is, deliberately, also how you escape a real one.
Do not run this on someone who is likely to panic, and never on a person who might actually fall for a real scam later , teaching someone that alarming red screens are a joke is exactly the wrong lesson. It works best as a demonstration, with you present and explaining as it happens.
What it cannot do
It does not scan, detect, transmit, install or change anything. There is no antivirus engine, no server call and no data of any kind involved. It is a coloured page with text on it, and it is not affiliated with any security vendor.

Fake virus alert questions
Do I have a virus?
Not from this page. It performs no scan of any kind , a web page has no access to your files. If you reached this page from a link and were alarmed, that is the point of the demonstration: real versions of this screen are scams.
How do I close a real one that will not go away?
Close the tab. If the page blocks that, force quit the browser entirely and reopen it without restoring the previous session. Never call a number shown on the page, and never install anything it offers.
Is this page dangerous?
No. It contains no code that touches your device, requests no permissions and stores nothing. It exists to look alarming and nothing more.
