Fake Virus Alert
The fake virus alert prank throws a flashing red "VIRUS DETECTED" warning across the screen — skull, encryption message, the works. Send the link, or open it on someone's device and go full-screen. It's an obvious gag the second they close it.
VIRUS
DETECTED
Press F11 for maximum realism. Tap or press Esc to exit.
Installed the crack fills the entire screen — no browser bar, no tabs, no giveaway.

For laughs only. Nothing here installs, downloads or damages anything — it's all harmless CSS/JS in the browser. It's a staple of April Fools' Day pranks and works any day of the year. Just keep it kind — see what makes a good prank.
Frequently asked questions
Is this a real virus?
No. It's a harmless web page that only shows a scary warning — no code is downloaded, run or installed. Close the tab and the "virus" is gone.
Can a fake virus link actually infect a device?
Not this one. It's pure HTML and CSS — no downloads, no exploits, nothing that touches the operating system.
