What kind of scam is "Virus Has Been Detected On Your Device"?

While examining deceptive websites, we discovered the "Virus Has Been Detected On Your Device" technical support scam. It makes false claims regarding infections on the visitor's device and it being blocked due to illegal activity. The goal is to trick victims into calling the provided fake helpline and thus entangling them into a scam.

Virus Has Been Detected On Your Device scam

"Virus Has Been Detected On Your Device" scam overview

When we entered a site promoting "Virus Has Been Detected On Your Device", we were presented with a page disguised as Microsoft's official website. The scheme quickly loaded a bogus system scan that was overlaid with pop-up windows. The topmost pop-up stated that a virus was detected on the visitor's computer. Hence, access to the system was blocked due to the illegal activity.

Throughout the scam, the visitor was urged to call the "Microsoft" support line. It must be emphasized that this scheme is in no way associated with the actual Microsoft Corporation.

Typically, after a victim calls the numbers promoted by tech support scams – the scammers (under the guise of "support", "expert technicians", etc.) request permission to access the "infected" device remotely. Often legitimate software like AnyDesk, TeamViewer, UltraViewer, or others are used to establish access.

How the scam progresses following this point can vary. Under the pretense of performing malware removal or other security support services, the cyber criminals can cause a wide variety of damage. For example, disable or remove genuine security programs, install fake anti-viruses, extract sensitive data, and infect the device with actual malware (e.g., trojans, ransomware, etc.).

Information of interest usually includes personally identifiable details, account log-in credentials (e.g., emails, social networking/media, messengers, streaming, gaming, FTPs, cloud storage, e-commerce, cryptocurrency wallets, money transferring, online banking, etc.), credit card numbers, and other finance-related data.

Criminals can obtain the information by tricking victims into giving it over the phone, typing it where it supposedly cannot be seen, entering it into phishing sites or files, etc. Alternatively, the vulnerable details can be extracted through information-stealing malware.

Furthermore, the "services" of scammers carry exorbitant fees. Cyber criminals prefer difficult-to-trace methods for the money transfer, such as digital currencies, gift cards, pre-paid vouchers, or cash hidden in innocuous-looking packages and shipped. What is more, successfully scammed victims are commonly targeted repeatedly.

To summarize, by trusting a scam like "Virus Has Been Detected On Your Device" – users can experience system infections, severe privacy issues, significant financial losses, and even identity theft.

If you cannot exit a deceptive webpage – use the Windows Task Manager to end the browser's process. Note that when you open the browser again, the previous browsing session must not be restored since that will reopen the scam page.

If you have disclosed your log-in credentials to scammers – change the passwords of all possibly exposed accounts and inform their official support without delay. And if you've provided other private data (e.g., ID card details, passport photos/scans, credit card numbers, etc.) – immediately contact the appropriate authorities.

If you have allowed scammers to remotely access your device – you must first disconnect it from the Internet, as the criminals may not need your consent to access the computer again. Secondly, uninstall the remote access software that the scammers used. Lastly, perform a full system scan with an anti-virus and remove all detected threats.

Technical support scam examples

We have investigated thousands of online scams; "!!Rootkit!! Malware Detected", "Threats Detected:Stuxnet", "Windows Key Code Is Not Valid And Seems Pirated", and "Critical Threat Detected: Adware App" are merely some examples of tech support schemes we have inspected recently.

The Internet is full of deceptive and malicious content. Common scam models include: tech support, virus/error alerts, cryptocurrency/prize giveaways, lotteries, and so forth. Online schemes can be basic and riddled with errors or competently made and disguised as content from legitimate entities.

How did I open a scam website?

Scam pages can be force-opened the moment a site using rogue advertising networks is accessed or when hosted content is interacted with (e.g., clicking buttons, text input fields, links, ads, etc.). Additionally, misspelling a website's URL can result in a redirect (or a redirection chain leading) to a deceptive webpage.

Spam browser notifications and intrusive ads endorse online scams as well. Adware also promotes this content through displayed ads or generated redirects.

How to avoid visiting scam websites?

We strongly recommend being vigilant when browsing since fraudulent and malicious content usually appears legitimate and harmless. We advise against using websites that offer pirated content or other questionable services (e.g., Torrenting, illegal streaming/downloading, etc.) since these sites are usually monetized via rogue advertising networks.

Furthermore, we recommend paying attention to URLs and entering them with caution. To avoid receiving deceptive browser notifications – do not permit suspicious webpages to deliver them (i.e., do not click "Allow", "Allow Notifications", etc.). Instead, ignore or deny notification delivery from such pages (i.e., select "Block", "Block Notifications", etc.).

What is more, all downloads must be performed from official and verified channels. It is just as important to treat installation processes with care, e.g., by reading terms, studying available options, using the "Custom/Advanced" settings, and opting out of all supplementary apps, extensions, tools, etc.

If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate all threats.

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.
