'Firewall Breach Detected' Pop-Ups

'Firewall Breach Detected' Pop-Ups Description

Type: Trojan

The 'Firewall Breach Detected' messages in your browser are not to be trusted. The alerts displayed on a Web page suggesting that your firewall was breached, are identified as fake security alerts. The 'Firewall Breach Detected' pop-ups are generated on deceptive sites, which include a screen capture of Support.microsoft.com and aim to convince the user to call a toll-free phone line like 844-699-8351. Legitimate computer support agents do not operate the 844-699-8351 phone line, as well as other lines advertised on the same 'Firewall Breach Detected' notifications.

The screen capture of Support.microsoft.com is a modified image that is used to claim credibility and fool the users into thinking that the security alert on their screens comes from Microsoft Corp. directly. The 'Firewall Breach Detected' warnings provide misleading information and cause program errors, which would lead to your browser being unresponsive. However, you should not panic when the 'Firewall Breach Detected' pop-ups appear. Do not call the 844-699-8351 phone line and cancel the automatic download of remote desktop software like TeamViewer and LogMeIn.
