What is Code #007d3Cx0d scam?

Typically, scammers behind tech-support scams like this attempt to trick users into installing unwanted software, providing remote access to a computer, or paying for unnecessary "technical" services.

In most cases, these websites display fake virus, error notifications claiming that users need to fix the problem immediately. Otherwise, there will be even more damage. It is important to mention that users do not visit tech-support scam websites intentionally.

Usually, these pages get opened via deceptive advertisements, other untrustworthy websites, or installed potentially unwanted applications (PUAs).

Typically, pages like this one display a message (or messages) stating that the computer is infected with malware and offer a telephone number for help with removing the malware. This page shows a message claiming that real-time virus protection is turned off and encourages to turn it on.

Then it runs a fake virus scan in a fake Windows Defender Security Center pop-up window and detects a number of viruses. It encourages to remove those viruses immediately. Otherwise, detected malware (spyware/riskware) might cause further damage.

This technical support scam's main purpose is to trick visitors into believing that they need to call the +1-844-342-2637 number for help with removing the detected threats.

It is common that scammers try to get unsuspecting users to install a some remote access desktop software so they could access their computers remotely and install real malware (e.g., ransomware, Trojan, malicious cryptocurrency miner), access personal files, or steal other sensitive data/information (e.g., login credentials, credit card details).

It is also common that scammers try to sell fake software or services. For example, they often try to get users to pay for a subscription plan of some fake software that does not remove any malware, fix errors (runs fake scans).

Quite often, technical support scams and other untrustworthy, deceptive websites are promoted through various potentially unwanted applications that users download, install on their browsers or computers unknowingly.

Apps of this type tend to be designed to display advertisements and (or) collect various data as well. They generate pop-up ads, coupons, surveys, banners, and other ads. More often than not, those ads promote other dubious websites or even distribute unwanted software.

Therefore, it is strongly recommended not to click on ads that appear because of installed PUAs. Also, many PUAs can access and collect Internet Protocol addresses, geolocations, addresses of visited websites, entered search queries, and other browsing data.

In some cases, they can read sensitive information (e.g., passwords, credit card details). If there is any reason to believe that an app of this type is already installed on a browser or the operating system, then it should be removed from it as soon as possible.

There are many different technical support scams. However, most of them display fake errors, virus notifications and encourage visitors to call the provided number to fix errors and remove threats.

It is important to mention that most of these scam pages are disguised as the official Microsoft websites (or legitimate Windows system notifications). However, the actual Microsoft company (its pages, products, or services) has nothing to do with these scams.

More examples of tech-support scams are "Your System Detected Some Unusual Activity", "Error Code: #0x564897", and "Suspicious Movement Distinguished On You IP".

How did potentially unwanted applications install on my computer?

A great number of PUAs are distributed by bundling them together with other programs (by including PUAs in downloaders, installers for those programs as extra offers). Typically, users can decline unwanted offers using "Custom", "Advanced", or other similar settings, or by unticking certain checkboxes.

However, when users leave those settings unchanged, they allow for bundled PUAs to be downloaded or installed too. In other words, users agree to unwanted offers when they leave default settings that certain downloaders, installers have unchanged.

Sometimes users cause unintentional downloads, installations through deceptive ads - by clicking on ads that can execute certain scripts.

How to avoid installation of potentially unwanted applications?

Applications should never be downloaded via third-party downloaders, eMule, torrent clients, or other Peer-to-Peer networks, from unofficial pages, or using other sources of this kind, or installed via third-party installers. It is common that their users download or install malicious, or other unwanted software.

Files and applications should be downloaded from official pasges and via direct links. Downloaders and installers with "Custom", "Advanced," and other similar settings in them (or checkboxes), should be checked for bundled applications.

Offers to  download or install bundled apps should be decline before finishing downloads, installations. Additionally, it is recommended not to click on ads if they are shown on shady websites. Quite often, those ads open other dubious pages or even cause unwanted downloads, installations.

Suspicious, unknown, or unwanted extensions, plug-ins, or add-ons installed on a web browser or programs of this kind installed on a computer should be removed. 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 remove fake pop-ups?

In most cases, pop-up scams do not infect users' devices with malware. If you encountered a scam pop-up, simply closing it should be enough. In some cases scam, pop-ups may be hard to close; in such cases - close your Internet browser and restart it.

In extremely rare cases, you might need to reset your Internet browser. For this, use our instructions explaining how to reset Internet browser settings.

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.

To minimize the risk of encountering pop-up scams, you should keep your Internet browsers up-to-date and use reputable anti-malware application. For this purpose, we recommend Combo Cleaner Antivirus for Windows.

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.
