Catch a Scam

Warns about deceptive links, fake alerts, fake sign-in pages, payment scams, and dangerous instructions before you click or act.

Catch a Scam warns you the moment a website tries to trick you, before you click, type, pay, or run anything. Most scams don't break in. They ask you to open the door: a fake virus alert that tells you to call "support," a "verify you're human" box that tells you to paste a command into your computer, a sign-in page that looks just like your bank, or a message demanding payment in gift cards. Catch a Scam spots these moments and shows a clear warning in plain language. FIVE SHIELDS, ALWAYS ON • Link Shield: checks links before you click. It catches look-alike addresses (like paypa1.com), links whose text names one site but go to another, and disguised addresses. Rest your mouse on a link for about a second for an online safety check. • Fake Alerts: spots pages pretending to be your computer or browser: fake virus warnings, fake "update your browser" screens, pages that try to lock your browser, and fake "verify you're human" checks. • Command Traps: warns when a page tells you to open Run or Terminal and paste something to "fix" or "verify" a problem. Real websites never need you to run a command on your computer. • Password Guard: marks password boxes. Red means the page imitates a well-known site, isn't encrypted, or would send your password insecurely. It never reads what you type. • Payment Guard: warns when a page pressures you to pay with gift cards, cryptocurrency, or a money transfer, and checks that the page asking for your card is genuine and secure. It never sees what you type. PLUS • Block Scam Sites: when Catch a Scam warns you about a page, you can block that site with one click so it never opens again in this browser. Change your mind anytime: unblock it from the toolbar menu. • Strict Mode: asks before opening a link Catch a Scam already flagged as dangerous. • Extension Watchdog (optional, off by default): alerts you when another extension gains access to every website or to sensitive data.
