Avoid the scam entitled "A virus has been detected on your computer"

Also Known As: A virus has been detected on your computer tech support scam
Damage level: Medium

What is "A virus has been detected on your computer"?

This is a typical tech support scam in which criminals claim to offer a legitimate technical support service.

Typically, the scammers responsible attempt to trick unsuspecting users into paying for supposedly legitimate software or services, or even installing a Remote Administration Tool (RAT), which would allow them to remotely access and control computers. In any case, you are strongly advised to ignore such scams and never trust the messages.

A virus has been detected on your computer scam

The main purpose of this technical support scam is to trick people into believing that their computers are infected with a virus and calling the +1 (603) 652-1871 number. It claims that a detected virus might compromise data such as passwords, browsing history, files stored on the computer, and other confidential information.

To prevent possible damage, users are urged to call the provided number within five minutes. This scam website may seem similar to an official Microsoft web page, however, none of the official Microsoft sites have anything to do with this site.

Typically, criminals behind these scams attempt to deceive people into paying for so-called "support" services or software and giving remote access to their computers. Through such access, the scammers might be capable of stealing sensitive information such as credit card details, passwords, installing malware (like ransomware, Trojans), accessing personal files, etc.

They can then misuse the accessed information to steal identities, personal accounts, make fraudulent purchases, transactions, and so on. You should ignore these scams. Note that users do not open these scam pages intentionally - in most cases, they are opened through other dubious websites, clicked deceptive ads, or by installed potentially unwanted applications (PUAs).

PUAs can open untrusted web pages and also collect various data relating to users' browsing habits. For example, IP addresses, entered search queries, addresses of visited pages, and geolocations.

In some cases, they target sensitive, personal details as well. Furthermore, PUAs often serve intrusive ads (coupons, banners, surveys, pop-ups, etc.), which can open untrusted web pages or even run scripts designed to download/install other unwanted software.

More examples of similar scams are "ERROR CODE 72", "Your Windows Is infected With (3) Viruses!" and "VIRUS ALERT FROM Windows".

Typically, these scam pages are disguised as official Microsoft websites claiming that they have detected a virus, error, etc., and encouraging users to call the provided number immediately. As mentioned, users do not often visit these sites intentionally. If your browser opens dubious, deceptive web pages automatically, it is likely that a PUA is installed.

How did potentially unwanted applications install on my computer?

Potentially unwanted applications are distributed using the download and installation set-ups of other programs. This distribution method is known as "bundling". Developers include PUAs into set-ups as 'additional offers' and hope that users will not decline them.

Typically, these offers are listed in "Custom", "Advanced", and other similar settings, however, many users fail to check and change these settings, thereby allowing additionally-included software to infiltrate. In some cases, rogue downloads and installations are caused by clicking deceptive advertisements that execute certain scripts.

How to avoid installation of potentially unwanted applications

Third party downloaders, installers, Peer-to-Peer networks (torrent clients, eMule, etc.), unofficial sites, freeware download pages, etc., often distribute PUAs or even malicious apps. Therefore, software and files should be downloaded only from official websites and through direct links.

Check all "Advanced", "Custom" and other settings, and decline offers to download or install additionally-included, unwanted apps. Do not click advertisements that appear on dubious, untrusted websites, since they can open other untrusted websites or cause unwanted downloads and installations.

Remove any, suspicious extensions, add-ons, and plug-ins installed on the browser. Also remove software of this kind that is installed on the operating system. 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.
