About this extension
ScamAvert helps you recognise and avoid online scams while you browse. It checks website addresses, links, sign-in forms, page behaviour and downloads for common signs of deception, then explains what looks suspicious.
Protection includes:
- Fake and lookalike website addresses
- Misleading links and redirects
- Suspicious sign-in forms and authentication-code requests
- Risky download flows and fake updates
- Copy-and-run tricks
- Fake warnings, pressure tactics and recovery-phrase requests
These checks run locally in your browser and do not require a ScamAvert account.
Sign in for additional tools:
- Website reputation checks
- Check a Link to investigate a suspicious URL without opening it on your computer
- Ask ScamAvert to analyse suspicious messages, links and images
ScamAvert keeps you in control. You can review findings, dismiss warnings, manage exceptions and continue to flagged destinations where supported.
ScamAvert helps identify scam indicators, but no protection can detect every scam and an unflagged website should not automatically be considered safe.
The ScamAvert Windows desktop app is optional. The browser extension works independently.
