“Firewall Breach Detected” virus displays a fake alarm message to misguide computer users

“Firewall Breach Detected” alert is a fake “error 0x8007042C” warning[1] notifying that Microsoft has detected a security breach from your IP address. It may look completely legitimate since scammers tend to intimidate victims by claiming that it may lead to data loss, identity theft, loss of passwords for social networking platforms and credit card details. The developers urge to contact “Microsoft Network Security Advisor” via toll-free +1 844 699 8351 number.

Most people get confused or scared due to the atmosphere created[2] to consult “as soon as possible” and as a result, unconsciously provide their personal number to the criminals. Thus, if you encountered a redirect to this alert pop-up, immediately close the window/tab and remove “Firewall Breach Detected” using a security software of your choice.

You should be aware that fake warnings are created to collect victims’ mobile numbers and later, offer their “help” to fix the nonexistent problem. Cybercriminals might choose between several ways to swindle money:

  1. Insist on purchasing sponsored or expensive security software that is unnecessary for you;
  2. Ask to provide access to manage your computer remotely and infect it with high-risk computer infections to continuously charge money for their services;
  3. Distribute malware through spam text messages.

If you click on any ads promoted by this warning pop-up, they might redirect you to suspicious websites containing malware-infected links or even trigger an automatic installation of one. Therefore, you should avoid clicking on vague ads and start “Firewall Breach Detected” removal. We strongly recommend using Reimage or any other trustworthy security system.

Potentially unwanted programs (PUPs) distribute the adware

You might encounter such scam due to the presence of a potentially unwanted program (PUP) or another plug-in in your computer. It sneaks into your system if you choose Quick/Recommended installation process and do not decline to install the adware bundled together. Dieviren.de team[3] warns that such occurrences are extremely frequent.

Developers intentionally hide the information about the PUP that comes as a package with other free software. Therefore, you should avoid downloading applications from unauthorized developers. If you do so, always select Advanced or Custom settings and un-tick all preselected boxes allowing to install the adware.

Besides, potentially unwanted programs (PUPs) spread via intrusive ads. Developers try their best to attract users into clicking on them. Never trust delusional advertisements offering free coupons, quickly earned prizes or secrets of an effective diet.

Kill “Firewall Breach Detected” warning pop-up automatically

Our IT professionals suggest you to remove “Firewall Breach Detected” with the help of a security application. As mentioned above, scammers might have infected your computer with malware remotely.
