The Diagnostic Scan Fake

The technician ran a scan, and the screen filled with red warnings; hundreds of errors, all serious. If a technician showed me errors on my computer sums up your afternoon, here's the part they didn't say: every computer shows those.
The message looks like this

Why this is a scam
The "diagnostic" is usually a built-in system log that every healthy computer fills with routine noise. Shown to someone who's never seen it, it looks like a disaster. That's the whole trick; nothing they showed you is evidence of a problem.
The price menu is the tell. Real repairs are quoted after diagnosing a specific fault. Scam repairs come pre-priced in tiers, because the "repair" is the same for everyone: a few minutes of pretend work.
This scam often follows a popup, a cold call, or a fake support number found through search. The scan is act two; the payment is act three.
Red flags checklist
Hundreds of "critical errors" found within minutes.
The scan happened during a call or session you didn't originate with the real company.
Scary but vague causes: failing drives, expired certificates, hackers.
Tiered pricing offered on the spot, before any specific fault is named.
Pressure to pay today, often by card read over the phone or gift card.
The manipulation tactic
Manufactured evidence. You're not being asked to trust a stranger's word; you're shown "proof" on your own screen, which feels impossible to argue with.
What to do, and what not to do
Don't pay for anything based on a scan you didn't ask for.
End the call or session; if remote access was on, turn off Wi-Fi and restart.
Never read your card number to a technician on the phone.
If you paid, call your card company now and dispute the charge.
If your computer genuinely misbehaves, choose a local repair shop yourself.
