Windows Warning Alert removal instructions

What is Windows Warning Alert?

"Windows Warning Alert" is a fake error message displayed by a malicious website and often visited by users inadvertently - they are redirected by potentially unwanted programs (PUPs) that infiltrate systems without permission (the "bundling" method). Furthermore, PUPs continually deliver intrusive online advertisements and record various data relating to browsing activity.

Windows Warning Alert adware

The "Windows Warning Alert" error message states that malware infections have been detected, personal data (logins/passwords, banking details, etc.) are at risk, and that the malware must be eliminated immediately. Victims are encouraged to contact "certified technicians" via a telephone number ("1-877-804-5390") provided. They are then supposedly guided through the virus removal process. Bear in mind, however, that, as mentioned above, the "Windows Warning Alert" error is fake. It attempts to scare and trick victims into calling and paying for services that are not required. Ignore this message. You can remove it simply by closing the web browser. PUPs generate pop-up, banner, coupon, and other similar advertisements using a "virtual layer" - a tool that enables placement of third party graphical content on any site. Therefore, displayed ads often conceal underlying content of visited websites, thereby significantly diminishing the browsing experience. In addition, these ads can lead to malicious websites - even accidental clicks might result in high-risk adware or malware infections. PUPs record IP addresses, URLs visited, pages viewed, search queries, and other similar information. This collected data might contain personal details that PUP developers share with third parties (who misuse personal details to generate revenue). Information tracking can result in serious privacy issues or even identity theft. For these reasons, uninstall all PUPs immediately.

"Windows Warning Alert" is virtually identical to Ransomware Attack Warning Alert, Windows Health Is Critical, Windows Defender Alert, and dozens of other fake error messages that also claim that the system is infected, missing files, or damaged in other similar ways. As with Windows Warning Alert, however, these pop-ups should not be trusted. Their purpose is identical - to generate revenue for the developers. PUPs have very similar behavior. By offering various 'useful features', they attempt to give the impression of legitimacy. Rather than providing any significant value for regular users, PUPs cause unwanted redirects, deliver intrusive advertisements, and continually record user-system information.

How did adware install on my computer?

To proliferate PUPs, developers employ a deceptive marketing method called "bundling" - stealth installation of third party applications with regular software/apps, since they know that users often rush the download/installation processes and skip steps. They hide bundled PUPs within the "Custom/Advanced" settings. Thus, skipping this section often leads to inadvertent installation of rogue applications.

How to avoid installation of potentially unwanted applications?

There are two simple steps you should take to prevent this situation. Firstly, closely analyze each download/installation step using the "Custom" or "Advanced" settings. Secondly, opt-out of all additionally-included programs and decline offers to download/install them. The key to computer safety is caution.
