Error # 0xx90025ee9 POP-UP Scam

Also Known As: "Error # 0xx90025ee9" virus
Damage level: Medium

What is Error # 0xx90025ee9?

"Error # 0xx90025ee9" is a fake error message, a security warning similar to many other fake messages such as Error Code :S112276, MS-SYSINFO32, System Firewall Has Blocked Some Features, etc.

Typically, fake error messages (or others) appear on untrustworthy, deceptive web pages. In most cases, users visit these sites unintentionally - they are redirected to them by potentially unwanted applications (PUAs) or intrusive ads. Users often install PUAs inadvertently.

The apps can lead to deceptive/untrustworthy websites, deliver ads, and record data relating to users' browsing activity.

The "Error # 0xx90025ee9" fake message states that there is a critical error on your Windows Operating System and the system is infected with spyware and other viruses. Scammers deploying this error message claim that your Facebook logins, credit card details, email account logins, and photos have been stolen.

To prevent further damage and fix the existing problems, you are encouraged to contact "Microsoft Support" via the telephone number (844-545-5419) provided. They also urge people not to close the security alert (Error # 0xx90025ee9) window, since this might cause even more problems.

Note that Microsoft and its support team has nothing to do with the "Error # 0xx90025ee9" pop-up or "Microsoft Warning Alert". Scammers claim to be Microsoft representatives to trick users into contacting them and paying for products and services that will supposedly fix the error (and solve other problems).

We strongly recommend that you ignore this fake message and simply close it. If the website prevents this, use Task Manager and end the browser process, or simply restart the computer. Do not restore the previously-closed session, since this will result in being redirected to the same website that caused "Error # 0xx90025ee9" in the first place.

Potentially unwanted applications responsible for these redirects also deliver intrusive ads. The ads are displayed through tools that enable placement of third party graphical content on any site, and thus often conceal underlying content of any visited website.

They can be very annoying and often redirect to untrustworthy/potentially malicious websites that can execute scripts that download and install malware. Many PUAs collect browsing-related data including IP addresses, keystrokes, URLs of visited websites, search queries, geo-locations, and so on.

The data might also include private information that is shared with third parties (potentially, cyber criminals) and misused to generate revenue. Information tracking apps can cause privacy/browsing safety issues or even lead to identity theft. We recommend that you uninstall all installed PUAs immediately.

Most fake error, virus alert, and other messages are identical. They are used to inform people of problems with their computers or operating systems, however, these statements are false and used only to trick people into paying for products or services that they do not need. Most PUAs are designed to generate revenue for their developers.

They are promoted as 'useful' apps, but this is merely an attempt to trick people into downloading them. Few of these applications deliver the functionality promised or any other value.

How did potentially unwanted applications install on my computer?

Some potentially unwanted applications can be downloaded from their official websites, however, most users install them inadvertently when software developers use a deceptive marketing method called "bundling" or through intrusive advertisements. "Bundling" is stealth installation of PUAs with regular software that is typically ad-supportive or free.

Developers hide bundled apps in "Custom", "Advanced" and other options/settings of the installation processes. Information about the presence of PUAs within the installation set-ups is often not properly disclosed.

In this way, users are tricked into installing them inadvertently. In some cases, potentially unwanted applications are installed when a third party software downloaders and installers are used.

How to avoid installation of potentially unwanted applications?

Avoid using third party software downloaders/installers and torrents. Download software using official and trustworthy sources only. Do not skip installations steps without first checking "Custom"/"Advanced" settings.

Deselect unwanted offers of additional software (in this case, potentially unwanted applications) and only then finish the installation or proceed to the next installation step. Be cautious when browsing the web - avoid clicking untrustworthy ads, especially when visiting suspicious web pages.

Malicious developers invest time and money into ad design and it can be difficult to determine if the intrusive ads are legitimate. If you are continually redirected to untrustworthy websites (gambling, pornography, adult dating, etc.), check your browser and computer for unwanted software.

Look for unknown/unwanted extensions, plug-ins, and add-ons, and uninstall them immediately. The same applies to programs installed on your computer. If your computer is already infected with PUAs, 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.
