Firewall Warning alert: your firewall sent no such message
Pop-ups claiming the Windows Firewall has blocked a threat, detected an intrusion, or put your network at risk, usually with a number to call before your connection is cut, are scam pages. Firewalls block traffic silently according to their rules, they do not post warnings in browsers, do not monitor you personally, and never ask for a phone call. The alert is a web page imitating a security product.
What to do
- Close the page or the whole browser with Task Manager (
Ctrl+Shift+Esc, End task) if it resists closing. Nothing on the page needs answering.
- Do not call the number and do not download any 'firewall update' or scanner the page offers.
- Check the real status yourself: open Windows Security from the Start menu and look at Firewall and network protection. Green check marks there are the actual state of the firewall.
- Run a full Windows Security scan if anything was downloaded.
- If the alerts keep coming from one site, avoid it, and clear that site's data in browser settings so stored pages stop resurfacing.
Red flags in firewall-themed scams
- It speaks for your router or ISP. Variants claim your internet provider detected hacking and will disconnect you. Providers do not send browser pop-ups like this.
- It invents an intrusion in progress, counting connections or showing a map. Real firewall logs are dull lists, not theater.
- It wants remote access 'to secure the network.' That access is the actual intrusion, and it is the moment real harm becomes possible.
- It asks for payment to renew firewall protection. The Windows Firewall is part of Windows and has no subscription.
Paid for 'network protection' already? Contact your card issuer or bank immediately and dispute the charge, then uninstall any software that was installed during the call and change passwords for email and banking from a clean device. Report it at reportfraud.ftc.gov, and consider a report at ic3.gov if money was lost.
Common questions
Can a website see that my firewall blocked something? No. A web page has no access to your firewall, its rules, or its logs. Any page describing your firewall's activity is making it up.
My router brand was named correctly. Is it real? Router brand names leak easily, browsers and network scans reveal the gateway model on some setups, and scammers also just guess the common brands. A correct guess is not verification.
