01What is Tech Support?

Tech support scams trick victims into believing their computer is infected with malware or has critical errors. Scammers use fake pop-up warnings, unsolicited phone calls, or fraudulent websites to create a sense of urgency, then charge for unnecessary "repairs" or gain remote access to steal data.

These scams often target less tech-savvy individuals, particularly older adults. The scammer may pose as a representative from Microsoft, Apple, or a well-known security company. They use technical jargon and legitimate-looking tools to appear credible.

The most dangerous variant involves the scammer gaining remote access to your computer via tools like TeamViewer or AnyDesk. Once connected, they can install actual malware, steal files, access banking credentials, or lock you out of your own device.

02How to identify this scam.

01Unsolicited phone calls claiming to be from Microsoft, Apple, or your ISP
02Pop-up warnings that say your computer is infected and provide a phone number to call
03Requests to install remote access software like TeamViewer or AnyDesk
04High-pressure tactics to pay immediately via gift cards or wire transfer
05Claims of "suspicious activity" detected on your computer
06Asking you to open Event Viewer to show harmless "errors" as proof of infection

03Real examples.

Case · 01

A full-screen pop-up appears while browsing, claiming Windows Defender has detected a trojan. It displays a phone number and says not to restart your computer or you'll lose all files.

Real Windows Defender never displays phone numbers
The pop-up can't be closed normally (it's just a web page)
Creates extreme urgency
Case · 02

You receive a call from someone claiming to be from your internet provider saying they've detected malware traffic from your IP. They offer to fix it remotely for $299.

ISPs don't proactively call about malware
They ask for remote access before explaining the issue
Payment requested via unusual methods

04What to do.

01Hang up on unsolicited tech support calls — Microsoft and Apple never cold-call
02Close browser pop-ups by force-quitting the browser (Cmd+Q or Alt+F4)
03Never give remote access to your computer to an unsolicited caller
04If you paid, contact your bank or credit card company for a chargeback
05If remote access was granted, change all passwords and scan for malware

05Report it.
