What is Microsoft Alert Your Data Is At Risk?

"Microsoft Alert Your Data Is At Risk" is another fake error similar to Computer Detected To Be Corrupted, Windows Malware Detected, Computer Detected To Be Corrupted, and many others.

Cyber criminals deliver this error using various deceptive websites that users often visit inadvertently - they are redirected by potentially unwanted programs (PUPs) or intrusive ads (displayed on other untrustworthy sites). Research shows that many PUPs infiltrate systems without consent.

Furthermore, these programs deliver intrusive ads and monitor web browsing activity by recording various sensitive information.

Microsoft Alert Your Data Is At Risk scam

The "Microsoft Alert Your Data Is At Risk" error essentially states that suspicious activity has been detected on the user's Internet Protocol (IP) address caused by a "harmful virus". It also states that the malware poses a threat to personal information and system stability. For these reasons, it must be eliminated immediately.

To receive help in resolving this issue, users are encouraged to contact 'technicians' via a toll-free telephone number ("1-866-218-1999") provided. These technicians supposedly guide victims through the malware removal process. This is a scam. "Microsoft Alert Your Data Is At Risk" is fake and has nothing to do with Microsoft.

In fact, cyber criminals generate revenue by tricking gullible users into paying for tech support that is not required. Therefore, ignore the "Microsoft Alert Your Data Is At Risk" error and never call the telephone number. You can remove this error simply by closing the web browser, however, some rogue sites use scripts that prevent users from closing browsing tabs/windows.

In these cases, close the browser using Task Manager or simply restart the computer. After re-running the browser, do not restore the previous session, otherwise you will reopen the malicious site/s.

As mentioned, potentially unwanted programs gather various information. Collected data (IP addresses, website URLs visited, pages viewed, search queries, etc.) typically includes personal information that is later shared with third parties (potentially, cyber criminals). These people misuse private data to generate revenue.

Therefore, having information-tracking apps installed can lead to serious privacy issues or even identity theft. Another important issue is display of intrusive ads. Most PUPs deliver banners, pop-ups, coupons, and other similar ads. To achieve this, developers employ various tools that enable placement of third party graphical content on any site.

Therefore, intrusive ads often conceal underlying content, thereby significantly diminishing the browsing experience. In addition, they might redirect to malicious sites or run scripts designed to download/install malware. Therefore, even a single click can result in high-risk computer infections. Uninstall all potentially unwanted programs immediately.

There are dozens of fake errors that share similarities with "Microsoft Alert Your Data Is At Risk". All claim that system is infected, missing files or damaged in other similar ways, however, these errors are designed only to extort money from unsuspecting users.

All potentially unwanted programs are very similar. By offering a wide range of "useful features", these programs attempt to give the impression of legitimacy, however, their only purpose is to generate revenue for the developers. Rather than giving any real value for regular users, PUPs pose a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

To proliferate PUPs, developers typically use the "bundling" method and the aforementioned intrusive advertisements. "Bundling" is essentially stealth installation of third party programs with regular software/apps. Developers hide "bundled" apps within "Custom/Advanced" settings (or other sections) of the download/installation processes.

These people do not properly disclose these installations. Furthermore, many users are likely to skip download/installation steps and click various advertisements - behavior that often leads to inadvertent installation of PUPs. In this way, users expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

Poor knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing software.

Intrusive ads typically seem legitimate, since developers invest many resources into their design, but most redirect to malicious websites (surveys, gambling, adult dating, and so on). If you encounter these advertisements, immediately eliminate all suspicious applications and browser plug-ins.

In addition, carefully analyze each step of the download/installation dialogs using the "Custom" or "Advanced" settings. Opt-out of additionally-included applications and decline offers to download/install them. We recommend that you avoid using third party downloaders/installers, since they are often monetized by promoting ("bundling") PUPs.

Download applications from official sources only, using direct download links. If your computer is already infected with PUPs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to identify a pop-up scam?

Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.

While in the majority of cases these pop-ups don't infect users' devices with malware, they can cause direct monetary loss or could result in identity theft.

Cybercriminals strive to create their rogue pop-up windows to look trustworthy, however, scams typically have the following characteristics:

  • Spelling mistakes and non-professional images - Closely inspect the information displayed in a pop-up. Spelling mistakes and unprofessional images could be a sign of a scam.
  • Sense of urgency - Countdown timer with a couple of minutes on it, asking you to enter your personal information or subscribe to some online service.
  • Statements that you won something - If you haven't participated in a lottery, online competition, etc., and you see a pop-up window stating that you won.
  • Computer or mobile device scan - A pop-up window that scans your device and informs of detected issues - is undoubtedly a scam; webpages cannot perform such actions.
  • Exclusivity - Pop-up windows stating that only you are given secret access to a financial scheme that can quickly make you rich.

How do pop-up scams work?

Cybercriminals and deceptive marketers usually use various advertising networks, search engine poisoning techniques, and shady websites to generate traffic to their pop-ups. Users land on their online lures after clicking on fake download buttons, using a torrent website, or simply clicking on an Internet search engine result.

Based on users' location and device information, they are presented with a scam pop-up. Lures presented in such pop-ups range from get-rich-quick schemes to fake virus scans.

How to prevent fake pop-ups?

To prevent seeing pop-up scams, you should visit only reputable websites. Torrent, Crack, free online movie streaming, YouTube video download, and other websites of similar reputation commonly redirect Internet users to pop-up scams.

What to do if you fell for a pop-up scam?

This depends on the type of scam that you fell for. Most commonly, pop-up scams try to trick users into sending money, giving away personal information, or giving access to one's device.

  • If you sent money to scammers: You should contact your financial institution and explain that you were scammed. If informed promptly, there's a chance to get your money back.
  • If you gave away your personal information: You should change your passwords and enable two-factor authentication in all online services that you use. Visit Federal Trade Commission to report identity theft and get personalized recovery steps.
  • If you let scammers connect to your device: You should scan your computer with reputable anti-malware (we recommend Combo Cleaner Antivirus for Windows) - cyber criminals could have planted trojans, keyloggers, and other malware, don't use your computer until removing possible threats.
  • Help other Internet users: report Internet scams to Federal Trade Commission.
