What is Windows Firewall Warning Alert?

"Windows Firewall Warning Alert" is a fake error message similar to Error 268D3-XC00037, Microsoft System Security Alert, Your Device Is Under Threat, and many others. This error is displayed by a malicious website. Research shows that, in most cases, users visit this site inadvertently - they are redirected by potentially unwanted programs (PUPs) that infiltrate systems without permission. In addition to causing redirects, PUPs deliver intrusive advertisements, gather sensitive information, and sometimes misuse system resources to run unwanted processes.

Windows Firewall Warning Alert adware

The "Windows Firewall Warning Alert" error claims that the system has detected spyware that poses a  threat to confidential data (logins, passwords, banking information, etc.) Therefore, users are encouraged to immediately contact "technical engineers" via a telephone number ["+1 (866) 475-7161"] provided. These people then supposedly guide victims through the malware removal process. In fact, the "Windows Firewall Warning Alert" error is fake and a scam. Cyber criminals claim to be certified technicians and offer technical support (which is not needed) for a certain fee. All claims regarding computer infections are false. In addition, criminals often attempt to gain remote access to users' computer. Once connected, they stealthily modify system settings and install malware. They then claim to detect additional issues and offer further help for an extra fee. In any case, never attempt to contact these people - the "Windows Firewall Warning Alert" error should be ignored. It can be removed simply by closing the web browser (preferably, via Task Manager) or rebooting the system (some malicious sites employ scripts that prevent users from closing the browser). Note that after re-running the browser, you should never click "Restore Previous Session" (or similar), otherwise you will return to the malicious website.

As mentioned above, potentially unwanted programs generate various intrusive ads (coupons, banners, pop-ups, etc.) that conceal underlying content, thereby significantly diminishing the browsing experience. Furthermore intrusive advertisements might lead to malicious websites and/or even run scripts that download/install malware. Therefore, even a single click can result in high-risk computer infections. Another downside is information tracking. Bear in mind that potentially unwanted programs continually gather IP addresses, URLs visited, search queries, keystrokes, geo-locations, and other information that is likely to contain personal details. Developers sell the information to third parties (potentially, cyber criminals) who misuse it to generate revenue. This behavior can lead to serious privacy issues or even identity theft. Some potentially unwanted programs are also designed to misuse system resources to run unnecessary processes (e.g., to mine cryptocurrencies). In doing so, PUPs significantly diminish overall system performance. You are strongly advised to eliminate all potentially unwanted programs immediately.

There are many fake errors such as "Windows Firewall Warning Alert". All claim that the system is infected, missing files, or damaged in other similar ways, however, these errors are designed only to extort money from unsuspecting users. Potentially unwanted programs also share many similarities. By offering useful features, PUPs attempt to give the impression of legitimacy and trick users to install, however, rather than delivering any real value for regular users, they pose a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

Potentially unwanted programs are proliferated using intrusive advertisements and a deceptive marketing method called "bundling". Therefore, due to the lack of knowledge and careless behavior of many users, PUPs often infiltrate systems without consent. "Bundling" is stealth installation of third party applications with regular software/apps. Developers are aware that many users rush download/installation processes. Therefore, "bundled" apps are hidden within "Custom/Advanced" options (or other sections) of these procedures. By skipping download/installation steps and clicking various dubious links/advertisements, users often expose their systems to risk of various infections.

How to avoid installation of potentially unwanted applications?

The key to computer safety is caution. Therefore, pay close attention when browsing the Internet and, especially when downloading/installing software. Bear in mind that criminals design intrusive ads to look legitimate. Once clicked, however, they redirect to dubious sites (e.g., gambling, pornography, adult dating, etc.) If you experience these redirects, uninstall all suspicious applications and browser plug-ins. Furthermore, carefully observe each window of the download/installation dialogs and opt-out of all additionally-included programs. Using a legitimate anti-virus/anti-spyware suite is also paramount.
