Every fake "virus alert" pop-up is built around one thing: a phone number. The flashing graphics, the alarm sound, the countdown — none of that is the actual danger. The number is. So we focused KinSentry's scam-page protection on the moment that matters most: stopping the pop-up and covering it with a clear, spoken warning, so the number is never read and never dialed.

Block the phone number, and you've blocked the scam — everything else is just theater.

The phone number is the whole scam

A tech-support pop-up screams that the computer is infected and insists your parent "call this number now." But nothing has actually happened to the computer. The pop-up is just a scary web page. The real trap springs the instant your parent picks up the phone — because on the other end is a person who will calmly talk them into handing over control and, eventually, money. (We break the full sequence down in the anatomy of a tech-support scam.)

That's why the phone number is the target. Remove it from the equation and the whole scam falls apart before it starts.

What's new: pop-up blocking that gets there first

When a page tries to display a fake virus-alert or tech-support scam pop-up, KinSentry now recognizes the pattern on the device, in real time, and takes over the screen before your parent has a chance to act on it:

Worth repeating to your parent: a genuine security warning from Microsoft, Apple, or their bank will never appear as a pop-up with a phone number to call. That combination is always a scam.

One layer of several

Scam pop-ups are just one of the tactics that target older adults — so blocking them is one layer of KinSentry's protection, not the whole thing. KinSentry also blocks the remote-access download sites scammers rely on, flags phishing emails in Gmail, Outlook, Yahoo and AOL, and warns on suspicious search ads. And on the Guardian plan, it alerts your family the moment any of it is blocked, so you know something happened even if it's never mentioned.

Private by design

All of this detection runs locally, in the browser. KinSentry never records the screen, never reads passwords, and never stores browsing history. When a scam is blocked, the only thing sent is the address of that blocked page — so your family can be alerted.

Protect your parent from the pop-up they'd otherwise call

KinSentry blocks scam pop-ups and remote-access sites automatically — and alerts your family the instant one is stopped.
