More about pop-up scams

Most scams of this type use scare tactics to promote legitimate or untrustworthy software, extract sensitive information, obtain remote access to a computer. They claim that a device is damaged, infected and encourage users to solve it as soon as possible. Also, these pages usually are disguised as legitimate websites.

More examples of similar scams are "Child Pornography Access Detected", "You've Visited Illegal Infected Website", "Norton Security - Your Pc Is Infected With 5 Viruses!". Typically, they are promoted through shady websites. In some cases, they are promoted using potentially unwanted applications (PUAs), for example, adware.

How did potentially unwanted applications install on my computer?

Typically, users install PUAs through installers for other programs, fake installers, shady advertisements. PUAs get installed together with other programs when users leave "Custom", "Advanced", "Manual", or other settings available installers unchanged.

Advertisements cause unwanted downloads or installations when designed to execute certain scripts. Fake installers used to distribute PUAs are promoted mainly on deceptive pages.

How to avoid installation of potentially unwanted applications?

Do not forget to check downloaders and installers with ticked checkboxes or settings like "Custom", "Advanced" for optional downloads or installations and deselect them. It should be done before downloading and installing software. Also, do not use questionable sources to download programs and files. Use official websites and direct links.

One more way to avoid unexpected downloads, installations is not to click on advertisements that shady pages have on them. 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.
