What is "McAfee - Your PC might be vulnerable"?

"McAfee - Your PC might be vulnerable" is a scam run on various rogue sites. While it is used to endorse the genuine McAfee anti-virus software, this promotion is not created by McAfee Corp. (the developers of McAfee anti-virus) but affiliates seeking to obtain illegitimate commissions.

However, the lack of such deception does not make these pages trustworthy. While this scam does promote the real McAfee anti-virus - it is done merely to obtain illegitimate commissions from unsuspecting users.

In some of these scams have been observed being used to spread malware (e.g., trojans, ransomware, etc.).

Online scams in general

"Your McAfee Subscription Has Expired", "McAfee - Your PC is infected with 5 viruses!", "Avira Free Security - Your PC is infected with 5 viruses!", and "fake Microsoft Edge Update" are some examples of similarly themed scams. The Internet is rife with a wide variety of schemes, ranging from fake virus alerts to bogus cryptocurrency giveaways

Scam sites are usually accessed inadvertently. Most users enter them via mistyped URLs or redirects caused by webpages using rogue advertising networks, deceptive browser notifications/ intrusive advertisements, or installed PUAs.

How did potentially unwanted applications install on my computer?

PUAs can have "official" promotional/download sites. However, they are most often downloaded/installed together with other programs. This marketing technique of packing regular software with unwanted/malicious additions - is called "bundling".

Intrusive adverts are known to proliferate PUAs as well. When clicked, the ads can execute scripts to make stealthy downloads/installations.

How to avoid installation of potentially unwanted applications?

It is recommended to research software and download it only from official/verified channels. Untrustworthy ones such as unofficial and freeware websites, Peer-to-Peer sharing networks, or other third-party sources - commonly offer bundled and harmful content.

When downloading/installing, it is advised to read terms, explore available options, use the "Custom" or "Advanced" settings, and opt-out of all supplements. It is just as important to exercise caution when browsing. Intrusive advertisements look legitimate yet redirect to dubious sites (e.g., gambling, pornography, adult-dating, etc.).

If ads/redirects of this kind are encountered, the system must be inspected and all suspicious applications and browser extensions/plug-ins detected - removed without delay. 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?
