We usually imagine that malicious computer infections are Trojans, ransomware applications, and other dangerous programs that can seriously damage the target system. However, Error 0x8007042c and similar fake alerts can also cause significant damage, if not to your system then to your wallet. This fake alert is part of technical support scams that are very popular nowadays. It is important that you ignore Error 0x8007042c and remove any unwanted programs that might be causing this fake pop-up to appear on your screen. For the best removal, scan your computer with a licensed security application because you may have many unwanted programs you do not even know about.

Error 0x8007042c and other technical support scams arrive with the intention to convince unsuspecting users that somehow there is something wrong with their systems, and thus they need to invest in some powerful security application. These fake alerts can jump into your screen when you click an outgoing link on a social engineering message, when you open a website that supports and promotes such notifications, or when you install a potentially harmful program that accommodates similar fake alerts. The bottom line is that if you see the Error 0x8007042c fake alert on your screen, somewhere the security or internet safety has been breached.

The problem with this error is that the code used is an actual Microsoft error message code, which usually appears when you have some sort of Windows Firewall glitch. So if you were about to look for information on the error message, you may find a lot of entries about Windows Firewall settings, and it may look as though Error 0x8007042c is a decent one, that tries to inform about serious security flaws in your system. However, unlike the original pop-up, this one is bound to be opened in your browser, and not on a separate system pop-up. When this fake alert pops up, here is an example of a text it might display:

Error: “ 0x8007042c”
FIREWALL BREACH DETECTED

It goes without saying that there is no need to call the given number because the entire message is a scam devised to trick you into contacting these criminals. The people on the other end will either try to make you purchase some sort of a product or will ask for your financial details (like your banking logins or credit card numbers). You should know better than to reveal such information to third parties.

If you see the Error 0x8007042c message on your screen, you need to close it immediately. If you cannot close the message, you press Ctrl+Shift+Esc simultaneously and kill your browser’s process through Task Manager.
