McAfee: SECURITY ALERT pop-up scam in detail

We have examined this scam website and found out that it displays different fake virus notifications (pop-ups) while attempting to close this page (before and during a fake system scan) or moving the mouse cursor outside the browser window. Both of the fake virus alerts are disguised as notifications from McAfee.

One of the fake messages claims that a computer is infected with five viruses. Another one says that not removing those viruses can result in permanent data loss and having credit card details and email, and social network accounts stolen.

More about similar pop-up scams

Developers of legitimate antivirus software like McAfee, Norton, Avira or other security solutions have nothing to do with such scams. In most cases, affiliates who advertise legitimate software in deceptive ways seek to collect illegitimate commissions.

More examples of similar scams are "McAfee - Your PC Might Be Vulnerable", "Avira Free Security - Your PC Is Infected With 5 Viruses!", "Norton Security - Your Pc Is Infected With 5 Viruses!". In some cases, these scams are promoted through shady applications.

How did potentially unwanted applications install on my computer?

Users cause unexpected downloads and installations by clicking advertisements designed to execute certain scripts, using fake installers downloaded from deceptive pages, or downloading or installing other programs without changing certain settings.

Users can deselect unwanted apps by unticking checkboxes or using "Custom", "Manual", "Advanced", or other settings available in downloaders and installers. Unwanted downloads/installations are caused by leaving those settings unchanged.

How to avoid installation of potentially unwanted applications?

Always use official pages and direct links as sources for downloading files/programs. It is not safe to use other sources such as unofficial pages, Peer-to-Peer networks, third-party downloaders, etc. Examine downloaders and installers with "Custom", "Advanced" or other settings and deselect unwanted apps before downloading or installing programs.

Also, do not click on advertisements showing up on pages related to gambling, pornography, adult dating, or other shady pages. 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.
