What kind of scam is "Your Computer Might Be Infected By Trojans"?

"Your Computer Might Be Infected By Trojans" is a fake error similar to "Windows Malware Detected", "Google Chrome Support Centre", "System Activation KEY Has Expired", and many others.

It is displayed by various rogue websites that users often visit inadvertently - they are redirected by intrusive advertisements (generated by other deceptive sites) or potentially unwanted programs (PUPs). In most cases, potentially unwanted programs infiltrate systems without permission.

As well as causing redirects, they deliver intrusive advertisements and gather various sensitive data.

"Your Computer Might Be Infected By Trojans" scam overview

This error message states that the system might be infected with a number of trojan-type viruses, since the system's activation key has expired. It is also stated that personal data (logins/passwords, private messages, etc.) has been stolen. Therefore, users must immediately contact 'tech support' via a toll-free telephone number ("+18663079527") provided.

"Your Computer Might Be Infected By Trojans" is a fake error and a scam. Cyber criminals attempt to scare and trick gullible users into calling and paying for tech support that is not required. Your computer is likely to be completely safe. Therefore, ignore "Your Computer Might Be Infected By Trojans" and never attempt to call the aforementioned telephone number.

This error can be removed simply by closing the web browser, however, note that some rogue sites employ 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 re-open the malicious websites.

Potentially unwanted programs deliver coupon, banner, pop-up, and other intrusive advertisements. To achieve this, developers employ various tools (e.g., "virtual layer") that enable placement of third party graphical content on any site. Therefore, delivered advertisements often conceal underlying website content, thereby significantly diminishing the browsing experience.

In addition, intrusive advertisements might redirect to malicious websites and execute scripts that download and install PUPs (or even malware). Therefore, even a single accidental click can lead to various computer infections. Another important issue is information tracking. Potentially unwanted programs are notorious for recording information that includes personal details.

Website URLs visited, pages viewed, queries entered into search engines, keystrokes, Internet Protocol (IP) addresses, Internet service providers (ISPs), geographic locations, and other collected data is later shared with third parties (potentially, cyber criminals).

These people generate revenue by misusing private information. Therefore, the presence of information-tracking app(s) can lead to serious privacy issues or even identity. You are strongly advised to eliminate all potentially unwanted programs immediately.

As mentioned above, "Your Computer Might Be Infected By Trojans" shares many similarities with dozens of other fake errors. All claim that the system is damaged (e.g., infected, missing files or similar), however, these errors are designed only to help developers generate revenue in dubious ways.

Potentially unwanted programs also share many similarities. By offering "useful features", PUPs attempt to give the impression of legitimacy, however, the only purpose of all PUPs 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?

Some PUPs have official download/promotion websites, however, due to the lack of knowledge and careless behavior of many users, PUPs often infiltrate systems without consent.

Developers proliferate these programs using intrusive advertisements and a deceptive marketing method called "bundling" (stealth installation of third party applications together with regular software/apps).

Developers do not disclose PUP installations properly - they hide them within various sections (typically "Custom" or "Advanced" settings) of the download/installation processes. Furthermore, many users click various advertisements and skip download/installation steps - behavior that often leads to inadvertent installation of potentially unwanted programs.

How to avoid installation of potentially unwanted applications?

The key to computer safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing software. Remember that developers invest a great deal of time and resources into intrusive ad design, thereby making them seem legitimate. Once clicked, however, they redirect to dubious websites (gambling, adult dating, pornography, and so on).

If you encounter these redirects, check the list of installed applications/browser plug-ins and eliminate any suspicious entries. Furthermore, select "Custom/Advanced" settings and carefully analyze each step of the download/installation processes. It is very important to opt-out of all additionally-included programs and decline offers to download/install them.

Your software should be downloaded from official sources only, using direct download links. Most third party downloaders/installers are monetized using the "bundling" method (promoting PUPs) and, therefore, these tools should never be used.

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.

Frequently Asked Questions (FAQ)

What is a pop-up scam?

Essentially, pop-up scams are messages designed to deceive users into performing certain actions. To elaborate, victims may be enticed/scared into calling fake support lines, allowing cyber criminals to access devices remotely, sending money to scammers, providing sensitive information, downloading/installing software, purchasing products, subscribing to services, etc.

What is the purpose of a pop-up scam?

The purpose of pop-up scams is to generate revenue for scammers. Cyber criminals primarily profit by acquiring funds through deception, promoting content (e.g., sites, software, products, services, etc.), selling/abusing private data, and proliferating malware.

Why do I encounter fake pop-ups?

Pop-up scams are predominantly endorsed via attachments/links in spam (e.g., emails, SMSes, PMs/DMs, social media/ forum posts, etc.) and redirects generated by websites utilizing rogue advertising networks, spam browser notifications, intrusive ads, misspelled URLs, and adware.

If you have allowed cyber criminals to access your device remotely – disconnect it from the Internet. Afterward, uninstall the remote access program that the scammers used (e.g., UltraViewer, TeamViewer, etc.), as they might not need your consent to reconnect.
