What does Windows Security Warning Popup Scam do?

Windows Security Warning Popup Scam is one of many fake Microsoft security alerts that have been very prominent lately. Fake Windows Defender Alert: Zeus Virus, Windows Firewall Blocked The Internet, and Windows Detected Alureon Virus Pop-up come from different developers, but the idea behind them is the same — to trick you into purchasing their services or promoted applications. Windows Security Warning Popup Scam does the latter as it is dedicated to promoting Mcafee Antivirus, a legitimate and useful anti-virus program. However, the people at Mcafee are probably not aware of the fact that their software is promoted by scammers and would definitely not approve it.

Our analysis has shown that this scam comes as a redirect from shady websites and is opened in a new tab or as a pop-up window. It is opened automatically and subjects you to false information. Therefore, that is why we call it a scam. When this scam loads, you will see a blue window. This window can be loaded in full-screen mode, so you may be unable to close it. So you have to press Esc or F11 to exit the full screen. However, you may not be able to close your browser because this scam page might prevent you. Therefore, you might have to kill your browser’s process from Task Manager.

This fake alert can present you with two types of texts when you get redirected to it. The first one is set to read the following:

Windows Security Warning:


Your Windows antivirus protection may not be sufficient enough. Get Mcafee Antivirus now and protect your computer from malware, viruses and online hackers.

It is strongly advised that you get protected now.


Browser: Firefox

Service Provider: [isp]

IP Address: [ip_address]

This window does not say that your PC is infected, but plainly promotes Mcafee Antivirus saying that you need to protect your PC from potential threats. The only deceptive thing about the version of this particular text is that it says that it is a “Windows Security Warning.” The other version of this scam has a different, deceptive message that reads:

Windows Security Warning

[ISP name] warning!
Viruses Distributing From

[ISP name] recommends to scan HDD with antivirus software. If you don't have antivirus or your antivirus is out of date get new antivirus here.

Step 1: download latest antivirus
Step 2: perform system scanning
Step 3: fix system vulnerability
Step 4 (optionaly): uninstall antivirus

Download recommended antivirus

This version says that your PC has been infected with malware from a specific location. The location varies depending on where you are also. The window includes the name of your Internet Service Provider (ISP) giving you the impression that your ISP is warning you about malware which is impossible for them to do in real life. Again, this window promotes an anti-malware program but does not include its name.
