PC Real or Fake Warning Checker: Answer 5 Questions
Look at the warning on your screen and answer honestly. Nothing you answer is sent anywhere — the checker runs entirely on this page. You can also print this page and keep it by the PC.
1. Does the warning show a phone number to call?
2. Did it arrive as a web page, a pop-up, or a loud voice message in your browser?
3. Is it asking for gift cards, bank transfer, cryptocurrency, or payment to “unlock” your PC?
4. Did someone call you claiming to be Microsoft, or ask to control your PC remotely?
5. Did the warning appear inside Windows Security (the shield icon) — not in your browser — after a scan?
Verdict: this is a scam. Do not call, do not pay, do not click anything on it.
Your one safe next step: close the browser without touching the message — hold the power button if you must — then reopen the browser and refuse any “restore pages?” prompt. Microsoft never shows a phone number, never asks for gift cards, and never calls you. If you already let someone in, follow the first-hour checklist.
Verdict: this could be a real Windows Security warning.
Your one safe next step: do nothing in a hurry. Open Windows Security yourself (Start → type “Windows Security”), read what it found under Protection history, and follow our guide to real Defender alerts. A real warning never asks for money or a phone call either.
Verdict: treat it as fake until proven real.
Your one safe next step: close it without clicking its buttons. Then check for yourself: open Windows Security from the Start menu and run a scan. If Windows Security shows nothing, the warning was theatre. When in doubt, never pay and never call — a real problem will still be there after you check calmly.
Why these five questions work
Real Microsoft warnings are quiet, live inside Windows Security, and never ask for anything. Fake ones are loud, live in your browser, and always want something — a call, a payment, or control of your PC. The questions above simply check which of those two families your warning belongs to. Print this page for anyone in your family who would appreciate having it on the fridge.
This checker gives guidance, not a guarantee. If money has already changed hands, contact your bank first, then follow the first-hour checklist.
