What is "Windows Defender Alert (0x3e7)"?

The "Windows Defender Alert (0x3e7)" pop-up window appears when visiting a deceptive website. This is a fake error alert. These notifications appear only on untrustworthy, potentially malicious websites that people end up visiting unintentionally - they are redirected to them by potentially unwanted applications (PUAs) that they have installed on their browsers or operating systems. Installation of these PUAs often occurs accidentally or unintentionally. When installed, these apps cause redirects to dubious websites, deliver ads, and gather information.

Windows Defender Alert (0x3e7) scam

According to the notification displayed in the "Windows Defender Alert (0x3e7)" pop-up window, Windows Defender has detected an error. It is stated that a Zepto virus was detected in the operating system registry. Scammers behind this fake error/virus alert claim that it has infected the system recently when a user visited a dubious website. People are urged not to shut down or restart their computers, since this might lock the computer permanently or result in permanent data loss. It is also stated that the computer's connection to the internet is already blocked, and to unblock it, users are required to contact "Technical Support" via the "+46 10 884 48 35" telephone number. Website visitors are urged to do this immediately. A Windows logo appears on this website - placed by scammers in an attempt to trick people into believing that Microsoft is involved. In fact, this is a deceptive website that scammers (cyber criminals) use to extort money from people. When contacted, the criminals offer purchase of various software or services. Generally, they claim that their services or products will solve the problem (in this case, an 0x3e7 error). Since this is just a scam, none of the statements (notifications and alerts) are accurate. These websites and associated pop-up windows should never be trusted. Close these sites immediately. If they cannot be closed in the normal way (by closing opened the browser window or tab), use Windows Task Manager by ending the browser process. Do not restore/open the previously closed (terminated) browsing session, since this will return you to the deceptive website.

Potentially unwanted apps are responsible for these redirects in most cases. They also feed users with various intrusive ads (coupons, banners, surveys, pop-ups, and so on), which are displayed using tools that enable placement of third party graphical content on any site. Therefore, they conceal underlying content of visited websites. Furthermore, when clicked, they trigger redirects to untrustworthy websites or run scripts designed to download/install other PUAs. Most unwanted apps collect data that developers share with third parties. They usually collect IP addresses, search queries, URLs of visited websites, geo-locations, etc. Unfortunately, they also gather personal and sensitive details (and share them). Some of the third parties might be cyber criminals. Therefore, having these apps installed can lead to various problems relating to browsing safety, privacy, and so on. In some cases, their use might cause identity theft.

There are various deceptive websites used to promote different fake notifications/alerts and other deceptive pop-up windows. Some examples of other scams of this type are "ERROR 0X1CXX560", "Activate Your Windows Now", and "Error Code XLMR01F7985". Generally, scammers use these websites to trick people into purchasing unnecessary software or using paid services that are not required. PUAs also have many similarities. They are promoted as useful and legitimate but usually cause unwanted redirects, gather data, and deliver ads rather than providing any real value.

How did potentially unwanted applications install on my computer?

PUAs can be downloaded and installed from their websites, however, most people are tricked into downloading and installing them. This happens when software developers use the "bundling" method or when users click dubious, intrusive advertisements. Bundling is essentially stealth installation of third party apps with regular software. Information regarding these apps is usually hidden in "Advanced", "Custom" or other similar options (or settings) of download/installation set-ups. Therefore, inadvertent installations or downloads usually occur when people do not check settings and leave them unchanged.

How to avoid installation of potentially unwanted applications?

Check all available checkboxes, "Custom", "Advanced", and other settings/options of software download or installation processes. Additionally, avoid using torrents, eMule (and other Peer-to-Peer networks), unofficial websites and third party software downloaders as sources for downloading software. Avoid clicking ads that look suspicious, since these may cause redirects to untrustworthy websites (gambling, pornography, adult dating, etc.). These websites promote PUAs. If you experience unwanted redirects (even without clicking ads) or intrusive ads, check the list of installed apps on your browser. If there are any suspicious or unwanted extensions, plug-ins, or add-ons, remove them immediately. The same applies to programs of this type that are installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
