I più spaventosi scherzi per computer gratuiti disponibili online. Tutti innocui, tutti divertenti.
The internet's scariest pranks — FBI warnings, ransomware, ghost messages, webcam hacks, and more. These horror-themed pranks cause maximum panic with zero actual danger. All 100% harmless. All completely free.
Cosa sono gli scherzi di paura?
Scare pranks are a special category of computer pranks designed to create a moment of genuine fear or panic — before the big reveal that it's all fake. They simulate terrifying scenarios: government investigations, ransomware attacks, haunted computers, and surveillance. The key to a great scare prank is that it looks absolutely real for about 10 seconds, and then becomes hilarious once the victim realizes they've been had.
The best scare pranks target modern digital fears — hacking, surveillance, identity theft — because those fears are real and relatable. Everyone has wondered what would happen if their computer was actually hacked, or if someone was watching through their webcam. These pranks let you play out that scenario (safely) and then laugh about it together.

Nothing triggers panic quite like an official-looking government warning. These pranks simulate law enforcement and government agency alerts that look terrifyingly authentic.
FBI Warning — You've Been Flagged
Our FBI Warning prank displays a full-screen alert claiming the user's device has been flagged for illegal activity. The official seal, the legal threats, the demand not to turn off the device — it's designed to cause immediate panic. The formatting, the language, and the overall presentation look like something you'd never want to see on your screen. The reaction? Always incredible. The relief when they find out it's a prank? Even better.
Prova Prank di Avviso FBICosa sono gli spaventi per scherzo?
The scariest prank on our entire site. A simulated ransomware attack with a realistic countdown timer, cryptocurrency payment demand, and a list of 'encrypted' files. This prank taps into one of the biggest cybersecurity fears of our time — and it does so with devastating authenticity. The countdown adds urgency, the Bitcoin address adds legitimacy, and the file list adds personal terror. Use this one only on close friends who will forgive you — eventually.
Prova il pranks di ransomwareConto bancario compromesso
A fake banking alert claiming your account has been compromised. It shows a realistic-looking banking interface with unauthorized transactions and a warning to 'act immediately.' Money is the most universal fear trigger — everyone cares about their bank account. This prank turns that fear into a hilarious 15-second roller coaster.
Prova lo scherzo di conto in bancaScherzi per computer per autorità e governo
These pranks simulate digital intrusions — hackers, spies, and surveillance. They play on the very real fear that someone could be watching or controlling your devices right now.
Prova La tua password è stata divulgata
One of our most effective scare pranks. It shows a notification that your webcam has been accessed by an unknown device, complete with a fake camera view and a 'recording' indicator. In an age of legitimate webcam hacking concerns, this prank hits way too close to home. The victim's instinct to cover their camera is immediate and visceral — which makes the reveal incredibly funny.
Prova il Prank della Webcam RubataTipografo fantasma — Il tuo computer è posseduto
The creepiest prank on our site. Messages start appearing on screen — typed by no one. 'I can see you.' 'Don't look behind you.' 'Your password is...' The typing happens at an eerie, deliberate pace that makes it feel genuinely supernatural. This prank works best in a dimly lit room for maximum creepy effect. It's the perfect blend of horror movie atmosphere and digital prank.
Provare il Prank della Webcam RubataHacking Simulation — You're Being Hacked
A realistic hacking attack simulation that makes it look like someone is actively breaking into the computer. Fake terminal commands scroll across the screen, progress bars show 'data extraction,' and dramatic 'ACCESS GRANTED' messages appear. For anyone who has seen the news about cyberattacks, this hits a nerve — which makes the reveal that much funnier.
Try Hacking Simulation PrankKeyboard Hacked — Every Key Does Something Wrong
You're typing an email and every key press produces something unexpected. Random characters, ominous messages, or complete gibberish appear instead of what you intended. The victim will frantically try different keys, restart their browser, even reboot their computer — but the 'hacked keyboard' keeps producing weird results. It's frustrating, confusing, and eventually hilarious.
Prova il Trucco del Tastiera HackatoLocalizzazione Tracciata — Qualcuno Sa Dov'è Tu
A fake map shows the victim's 'real-time location' being tracked by an unknown entity. The crosshair on the map moves, the tracking status updates, and a creepy 'subject acquired' message appears. Location tracking is a real concern, and this prank exploits that fear perfectly. The moment they think someone actually knows where they are — that's the scare. The moment they realize it's a prank — that's the laugh.
Provare il Prank del Deepfake DettoLa tua posizione è stata tracciata — Qualcuno sa dove sei
These pranks lean into supernatural and horror themes — ghostly messages, AI gone wrong, and things that go bump in the digital night. They're perfect for Halloween or late-night pranking sessions.
Ghost Typist — Il Prank Più Spaventoso della Rete
We've already mentioned this one, but it deserves a second mention in the horror section because it's genuinely the creepiest experience you can create with a web browser. The slow, deliberate typing. The ominous messages. The feeling that someone — or something — is controlling your computer. Dim the lights, set the mood, and watch your friend's face as the messages appear.
Provare il Prank della Webcam RubataAI andata in fuga
What happens when AI decides it doesn't want to follow instructions anymore? This prank simulates an AI assistant that starts giving increasingly sinister responses, eventually claiming it has 'taken control' of the device. In an era where AI anxiety is at an all-time high, this prank feels uncomfortably plausible. The slow escalation from helpful to menacing is what makes it so effective.
Spaventi Horror e SupernaturaliTracciato la posizione
A fake deepfake detection alert that claims AI has been used to manipulate photos or videos. The technical language, the warning icons, and the 'detection report' all look like they came from a real cybersecurity tool. This prank is especially effective on people who are aware of deepfake technology — they'll recognize the threat immediately, which makes the panic more intense and the relief more rewarding.
Prova il Prank di Deepfake DettoMatrix Rain — Il Mondo Digitale Sta Rompendo
Not exactly a 'scare' in the traditional sense, but the Matrix rain effect creates an incredibly unsettling atmosphere. When green code starts cascading down the screen, it feels like the digital world is glitching — or that you've somehow entered the Matrix itself. Use it as a backdrop for other pranks or on its own for a creepy, cinematic experience.
Lo Scrittore Fantasma — Il Prank più Spaventoso della ReteCrashes del Sistema — Fallimento a Cascata
These pranks simulate the most terrifying thing that can happen to a computer user — a system crash. Blue screens, error cascades, and frozen displays that make the victim think their device is seriously broken.
Schermo Blu della Morte (BSOD)
The granddaddy of all system crash pranks. Our BSOD simulator is a pixel-perfect recreation of the Windows Blue Screen of Death — complete with authentic error codes, technical information, and that unmistakable shade of blue. It triggers an immediate fight-or-flight response in anyone who has ever experienced a real BSOD, which is basically everyone who has ever used Windows. The moment of panic, followed by the realization that it's just a webpage — that's what makes this the most classic scare prank of all time.
Try BSOD PrankProva il Prank dell'Intelligenza Artificiale Fuori Controllo
One error is bad enough. A cascade of errors flooding the screen is pure chaos. System Error simulates an unstoppable wave of error messages, warning dialogs, and system alerts that multiply faster than the victim can close them. The screen fills with pop-ups, the sound of error messages stacks up, and the victim is left feeling completely helpless. Then you tell them it's a prank, and the chaos becomes comedy.
Prova Errore del Sistema PrankBlocco della Schermata — L'Orrore Silenzioso
Sometimes the scariest thing is silence. A frozen screen doesn't respond to clicks, keyboard presses, or anything else. The victim tries everything — clicking, pressing keys, even the power button. Nothing works. Is the computer broken? Is it hacked? Is it frozen? The uncertainty is what makes this prank so effective. It's simple, subtle, and deeply unsettling — especially for less tech-savvy victims.
Errore del Sistema — Fallimenti a CatenaAggiornamento Falso del Sistema — Il Sogno da 99%
A system update that gets stuck at 99% — and never finishes. The message says 'Do not turn off your computer' and the progress bar sits there, mocking the victim with how close it is to completion. The anxiety builds as they wonder: should they wait? Should they force restart? What if they lose everything? It's the most relatable tech fear turned into a prank.
Prova Aggiornamento del Sistema PrankPrivacy e Violazione dei Dati — Scherzi di Paura
These pranks exploit modern fears about data breaches, privacy violations, and identity theft. They simulate scenarios where personal information has been exposed, which is a genuine concern for most internet users.
Password svelata — I tuoi credenziali sono esposte
A fake data breach notification that claims the victim's passwords have been found in a leaked database. It shows fake credentials, lists 'compromised' sites, and creates a sense of urgent vulnerability. Password leaks are a real and common occurrence, which makes this prank feel uncomfortably real. The victim's first instinct will be to check if their actual passwords have been leaked — which is exactly the kind of panic that makes this prank so effective.
Prova il Prank della Password RubataStoria del Browser Esposta — Le Tue Ricerche Sono Pubbliche
A fake alert claiming the victim's browser history has been publicly leaked. It displays fake 'embarrassing' search queries and a countdown to full public release. This prank works because everyone has searched for things they'd rather keep private — and the thought of those searches being made public is genuinely terrifying. The countdown timer adds urgency, and the fake searches are relatable enough to feel real.
Prova il Prank sulla Storia del BrowserProva il Prank Browser History Leaked
A fake dashboard showing all the victim's smart home devices being controlled by an unknown hacker. Lights flickering, thermostat changing, door locks clicking — the interface looks like a real smart home app, which makes the 'attack' feel devastatingly plausible. This prank is especially effective on people who actually have smart home devices, because they know exactly how scary it would be to lose control of them.
Prova il Prank della Casa Intelligente RubataVPN Leaked — Your Privacy Is Gone
For anyone who uses a VPN for privacy, the idea that their VPN has been compromised is terrifying. This prank shows a fake VPN disconnection notification with the victim's 'real' IP address and location revealed. The technical language and realistic interface make it look like a genuine security breach — until the reveal that it's all just a harmless prank.

Scare pranks are powerful — they can create genuine moments of fear. That's what makes them fun, but it's also why you need to be thoughtful about how you use them. Here are our guidelines for responsible scare pranking:
1. Know Your Victim
Only use scare pranks on people who you know will find them funny afterward. If someone is particularly anxious, has a heart condition, or is going through a stressful time, choose a milder prank instead. The goal is shared laughter, not genuine distress.
2. Reveal Quickly
The sweet spot for a scare prank is 5-15 seconds of panic followed by an immediate reveal. Press Escape, close the tab, or just tell them it's a prank. The longer you let someone believe it's real, the less funny it becomes. A quick reveal turns fear into laughter; a long delay turns fear into resentment.
Sii Lì per la Reazione
The best part of a scare prank is the reaction — the wide eyes, the gasp, the moment of realization. If you're not there to see it, you're missing the whole point. Position yourself so you can watch, and be ready to reassure them immediately.
Come Farsi Scare Pranks Divertenti (Non Offensivi)
Scare pranks and workplaces don't mix. A fake ransomware attack during a workday could cause someone to report it to their IT department, call the police, or even trigger a real incident response. Save the scare pranks for casual settings with friends who you know will laugh.
Scegli il Prank Giusto per la Persona Giusta
Not every scare prank is right for every person. Tech-savvy friends will appreciate the Hacking Simulation or Ransomware because they understand the technical references. Non-tech-savvy people might find simpler pranks like BSOD or Screen Freeze more effective because they're more believable to someone who doesn't know how computers work.
6. Never Prank About Real Emergencies
Don't use scare pranks during real emergencies or serious situations. If someone's actually worried about a real cybersecurity threat, financial issue, or legal matter, a scare prank is the last thing they need. Timing is everything.
La Psicologia dei Prank di Paura
Perché i trucchi di paura funzionano così bene? Ciò dipende da pochi principi psicologici:
- Aversione alla perdita — People feel the pain of losing something (files, money, privacy) about twice as strongly as the pleasure of gaining it. Scare pranks trigger loss aversion by simulating the threat of losing something valuable, which creates an intense emotional response.
- La perdita avversione — We're wired to take official-looking warnings seriously. When a prank shows an FBI seal, a banking interface, or a cybersecurity alert, our brain assumes it's real because it looks authoritative. This is why our FBI Warning and Ransomware pranks are so effective.
- Catarsi — The relief that follows a scare prank is called catharsis — the emotional release that comes when a perceived threat turns out to be harmless. This relief feels genuinely good, which is why both the prankster and the victim end up laughing. The bigger the scare, the bigger the catharsis.
- Bias di autorità — Scare pranks create a shared story that you'll both remember and laugh about for years. 'Remember when I thought the FBI was after my laptop?' becomes an inside joke that strengthens friendships.
