It shows a deceptive message claiming that the operating system is infected with seven viruses. It urges visitors to remove those viruses to protect personal and banking data.

Also, this website has the "REMOVE VIRUS" button and a countdown timer showing how much time has been left until the system is completely damaged. After clicking the "REMOVE VIRUS" button, a download page for an application called OneBlock pop-ups up in a smaller window.

Similar scams in general

Websites running pop-up scams (showing fake warnings or other messages) usually are disguised as legitimate pages. They are used to promote shady software, extract money or personal information from unsuspecting users, obtain remote access to computers, or even distribute malware.

Examples of similar scams are "Your Windows OS Is Damaged", "1978 Act Of Protection Of Children", and "Your Windows Got Corrupted Due To Virus".

How did I open a scam website

Most websites running pop-up scams are promoted via untrustworthy advertisements and web pages that use rogue advertising networks (e.g., illegal movie streaming pages, torrent sites, etc.). Users do not open these sites on purpose. Advertising-supported apps and notifications from dubious pages can also be used to promote websites showing fake/deceptive pop-ups.

How to avoid visiting scam pages?

Do not trust advertisements and links on suspicious websites (or notifications from pages of this kind). Download apps from official pages and stores only. Read reviews before downloading apps (avoid downloading apps with no or few reviews).

Check downloaders and installers for unwanted apps (and deselect them) before downloading and installing programs. If your computer is already infected with unwanted apps, 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.
