Tech-Support Scams
A frightening pop-up says your computer is infected and to call a number — or “Microsoft” rings out of the blue. It’s designed to panic you into handing over control. Here’s how it works, and how to shut it down.

Pop-up · “Microsoft Security”
“VIRUS DETECTED! Your computer is locked. Call Microsoft Support now: 1-800-…”
Tech-support scams prey on a very reasonable fear: that something is wrong with your computer. A scary pop-up or an official-sounding call convinces you there’s a virus — then the “help” that follows is the actual attack.
They target older adults especially, and the damage is real: victims are charged for fake “fixes”, tricked in refund cons, or watch a stranger open their bank account on a shared screen. The defence is one firm rule.
The one fact that ends this scam
Microsoft, Apple, and your internet provider will never call, email, or pop up a warning telling you to phone them about a virus — and no real security alert comes with a number to call.
If anyone asks to remotely access your computer or to pay for “support” you didn’t seek out, it’s a scam. Don’t call, don’t click, don’t let them in.
How Tech-Support Scams Work
The scare
A full-screen pop-up (often with a blaring alarm and a “locked” browser) shouts that your computer is infected and gives a number to call — or an unsolicited caller/email claims to be from Microsoft, Apple, or your internet provider about a “problem”.
The call
You call the number, worried. A calm, professional “technician” answers and offers to fix it. Because you called them, it feels safe.
Remote access
They talk you into installing a screen-share app (AnyDesk, TeamViewer) so they can “see the problem”, then point at ordinary system messages as “proof” of a virus to convince you it’s serious.
The payment
They charge you to “fix” it, or run a fake refund that “accidentally overpays” you and asks you to send the difference back — and with your screen shared, they can open your banking and drain it directly.
The Two Ways They Reach You
The pop-up you call
A fake “virus” page hijacks your browser — often with an alarm sound and a screen that won’t close — and pushes you to phone the “support” number. Nothing is actually infected.
The call, email, or invoice that reaches you
An unsolicited caller claims to be “Microsoft” or your ISP, or a fake invoice says your antivirus just auto-renewed with a number to “cancel or get a refund.” Same trap, different door — see our subscription-refund alert.
Red Flags
- A pop-up or message saying your computer is infected and giving a phone number to call.
- An unexpected call, email, or text claiming to be Microsoft, Apple, or your internet provider about a virus or “problem”.
- Any request to install AnyDesk, TeamViewer, or other remote-access software.
- Being asked to pay for “support” — especially by gift card, bank transfer, or crypto.
- A “refund” that overpays you and asks you to return the difference.

Open the Phone Number Scam Checker →How to Protect Yourself
- Never call the number in a pop-up or unsolicited “virus” warning.
- If a scary page won’t close, force-quit the browser or restart the computer — the “warning” is gone.
- Never let anyone who contacted you remotely access your computer.
- Remember: real companies don’t cold-call you about viruses or ask you to pay by gift card.
- Keep your device and software updated, and use a genuine antivirus you chose yourself.
Can You Get Your Money Back?
Honest answer: it depends almost entirely on how you paid and how fast you act. Speed is everything — report within hours, not days.
- Credit cardOften
You can dispute the charge (a “chargeback”) through your card network. The strongest protection of any payment type.
- Bank transfer, UPI or debit cardSometimes — if you’re fast
Report within hours so the bank can try to freeze the receiving account before the money is moved on. In India, call 1930 or file at cybercrime.gov.in immediately.
- Payment apps (Zelle, Venmo, Cash App, PayPal)Varies
Often treated like cash. PayPal “Goods & Services” has buyer protection; “friends & family” and most instant transfers usually don’t. Report to the app and your bank.
- Gift cardsRare
Contact the card issuer immediately — occasionally they can freeze an unredeemed balance. After that, it’s almost always gone.
- CryptocurrencyHardest — usually not
Crypto transfers are irreversible and cross-border. Recovery is rare, but act fast: report the transaction (with the wallet address and transaction hash) to the exchange involved and to law enforcement. If the funds land in a regulated exchange, it can sometimes freeze them.
What Actually Helps
- 1Act immediately — the faster you report, the better any chance of a freeze or reversal.
- 2Contact your bank, card issuer, or payment app now and ask them to dispute, recall, or freeze the payment.
- 3Report it to the authorities — here’s who to contact wherever you live. You often need a police or report reference number to pursue a dispute.
- 4Save everything: transaction IDs, wallet addresses, screenshots, phone numbers and usernames.
!Beware “recovery” scams
After you’ve been scammed, you may be contacted by someone promising to recover your money for an upfront fee, a “tax”, or a crypto payment. That is a second scam — often run by the same people, working from lists of known victims. No legitimate agency, lawyer, or service guarantees recovery or asks you to pay up front, and real police and banks never charge you to investigate. Never pay anyone to get your money back.
Where to Report — Wherever You Are
If you paid or shared bank access, contact your bank or card issuer immediately to block the card and dispute the charge — then report it. Speed matters most in the first hour. Reporting fast gives the best chance of freezing the money before it’s gone. Then file with your national authority:
India — Helpline 1930 · cybercrime.gov.in
Report in the first hours (the “golden hour”) to freeze funds. Run by I4C, Ministry of Home Affairs.
United States — FTC · FBI IC3
reportfraud.ftc.gov and ic3.gov.
United Kingdom — Action Fraud
actionfraud.police.uk · 0300 123 2040 (in Scotland, call Police Scotland on 101).
Australia — Scamwatch (National Anti-Scam Centre)
scamwatch.gov.au.
Canada — Canadian Anti-Fraud Centre
antifraudcentre-centreantifraude.ca · 1-888-495-8501.
Anywhere else: contact your bank and local police right away, and search “report a scam” plus your country. For cross-border cases, econsumer.gov collects international complaints. Beware anyone who later offers to “recover” your money for an upfront fee — that is a second scam.
Frequently Asked Questions
Will Microsoft or Apple ever call me about a virus?
No. Microsoft, Apple, and internet providers do not monitor your computer and will never cold-call, email, or pop up a warning telling you to phone them. Any contact like that is a scam.
A pop-up locked my screen and says to call a number — is my computer infected?
Almost certainly not. It’s a scare page running in your web browser, not a real infection. Don’t call the number. Close the browser (force-quit it) or restart the computer, and the “warning” disappears.
I let a “technician” remote into my computer. What do I do now?
Act fast: disconnect from the internet, uninstall the remote-access app, and from a different device change your banking and email passwords and turn on two-factor authentication. Call your bank on its official number to watch or freeze the account, run a malware scan, and report it.
They asked me to pay by gift card, or “refunded” me and want the difference back. Real?
Both are scams. Genuine tech support doesn’t take gift cards, and no real refund overpays you and asks you to return money. Stop and don’t send anything.
How do I get a genuine computer problem fixed safely?
Contact the company through its official website or app that you navigate to yourself, or use a reputable local technician you found independently — never a number from a pop-up, email, or unsolicited call.
