Microsoft Called About Your Computer. Is It Real or a Scam?

No Verification Needed — This Is Always a Scam

Unlike some other scenarios, you do not need to check any details to know this call was fraudulent. Microsoft's policy is unambiguous: they do not monitor individual computers and will never proactively call you about a virus, security problem, or error on your device. This is true regardless of what the caller said, what number appeared on your caller ID, or how official they sounded.

• Microsoft does not monitor your computer. Microsoft has no system that detects viruses or errors on individual customer computers and sends technicians to call. Microsoft's own support page states this explicitly: "Microsoft will never proactively reach out to provide unsolicited PC or technical support."
• Did a browser pop-up display a warning and a phone number? Microsoft never uses browser pop-ups with phone numbers. Legitimate Windows error messages appear in the operating system, not in your browser. A browser pop-up with a phone number is always a scam — close the browser tab immediately (if the browser is frozen, restart your computer).
• Did they say your Windows license has expired or been compromised? Windows license issues are handled through official Microsoft channels and your account at microsoft.com — never by an unsolicited phone call. Any caller claiming your license is expired or your computer is "infected" is running a script designed to create panic.
• Did they ask to remotely access your computer? This is the core goal of the scam. Once they have remote access, scammers can install software that gives them permanent access, steal passwords and banking information, and lock your computer to demand ransom. If you gave access, act immediately — see the section below.
• Did the caller ID show "Microsoft" or a 1-800 number? Caller ID can be spoofed to display any name or number. A caller ID showing Microsoft is not verification that the call is from Microsoft. The only safe assumption is that any unsolicited call about your computer is a scam.

What This Scam Is and How It Works

This is called a tech support scam. It arrives two ways: a phone call claiming to be from Microsoft, Windows, or a security company; or a browser pop-up displaying a warning and a phone number to call. Both lead to the same place — a person who asks to remotely access your computer to "fix" the problem.

Once remote access is granted using tools like TeamViewer or AnyDesk, the scammer shows you fabricated "evidence" of infection (normal system logs made to look alarming), then demands payment — typically $200–$500 — for fake repair services. In more aggressive variants, they transfer money directly from visible banking sessions or install software that gives them future access.

The FTC reported $924 million lost to tech support scams in 2024 — the highest of any impersonation category. Adults 60 and older account for nearly half of all reported losses. These operations run from overseas call centers with scripts, performance targets, and even customer service managers.

What If It Was an Email, Security Alert, or Pop-up?

The same criminals reach people through fake Microsoft emails, "security alerts," and browser pop-ups — not just calls. A phone call or pop-up demanding you call a number is always a scam, but email is trickier, because Microsoft does send some genuine security messages. Here's how to tell them apart safely.

• "Unusual sign-in activity" or "your account was hacked" emails. Microsoft does send real alerts about unusual sign-ins, and genuine ones come from account-security-noreply@accountprotection.microsoft.com. But that address can be spoofed, so never decide by the sender or logo alone. Do not click the "review activity" button. Instead, open a new browser tab, type account.microsoft.com yourself, sign in, and check Security → Recent activity. If the sign-in isn't listed there, the email is phishing — delete it.
• A "single-use code" you didn't request. Getting an unexpected verification code usually means someone entered your email at the sign-in page and is trying to break in — but they can't get in without the code, so your account is safe as long as you never share it. Microsoft and the "Microsoft account team" will never call, email, or text asking you to read a code back. Anyone who asks for your code is a scammer.
• Fake invoices, renewals, or "Microsoft 365 / Defender / McAfee" charges. Scam emails claim you were billed for a subscription and give a number to "cancel." Don't call it — that number reaches the scammer. Check any real subscription or charge by signing in at account.microsoft.com or your bank's app directly.
• A browser pop-up with a warning and a phone number. Microsoft never puts a phone number in an error message or pop-up. Don't call it. Close the tab — and if the browser is frozen, hold the power button to restart. The pop-up itself can't harm your computer; only calling the number or giving access can.

In every version, the rule is the same: don't click the link, don't call the number, and don't share a code. Verify anything by going to Microsoft yourself.

Common Questions

How to Reach the Real Microsoft and Check Your Account

After any suspicious message, reach Microsoft on your own terms. The most important thing to know: Microsoft does not make unsolicited support calls, and its error messages never contain a phone number — so any number that calls you or appears in a pop-up is a scam. Avoid searching "Microsoft support phone number" in a hurry, too, because scammers buy ads that place fake numbers at the top of the results.

You can confirm almost everything yourself by signing in to your Microsoft account at account.microsoft.com/security (the official "Microsoft login"). There you can review recent sign-in activity, see active subscriptions and charges, and change your password or turn on two-step verification. Type the address into your browser yourself — never follow a link or a number from an email, pop-up, or caller.

If your browser is frozen on a pop-up, hold the power button to force shut down. Your computer is not infected — the pop-up itself cannot harm your computer. Only calling the number or giving access can.
