"McAfee - A Virus Has Been Found On Your PC!" scam overview

This scheme is presented as the McAfee anti-virus – using its name, logo, and other graphical elements. When the website promoting this scam was accessed, the page displayed a pop-up window. The message therein stated that a virus was detected on the visitor's device. It warned that computer data may get deleted.

The pop-up urged to scan the system and eliminate the threat. After we pressed the "Scan PC" button, the scheme displayed a fake interface of the McAfee anti-virus and imitated a system scan. While the bogus scan was running, multiple threat reports were shown on the right side of the page. Then the scheme presented us with a pop-up used by versions of the "McAfee - Your PC is infected with 5 viruses!" scam.

As previously mentioned, this deceptive content is in no way associated with McAfee, Windows, or any other legitimate products/companies.

In most cases, schemes like "McAfee - A Virus Has Been Found On Your PC!" are used to endorse fake anti-viruses, adware, browser hijackers, and PUAs – under the guise of "useful" and "advantageous" tools. We have even discovered instances where such scams proliferated trojans, ransomware, and other malware.

It is noteworthy that schemes of this kind may abuse the affiliate programs of legitimate software/services and redirect to their official websites. In these cases, the scammers seek to obtain illegitimate commissions for the fraudulent promotion.

However, even if a redirect lands on a legitimate site – the scam must not be trusted. Firstly, it could be a malicious webpage disguised as one belonging to reputable content, and secondly, where a scheme redirects may change. Therefore, we strongly advise downloading only from official and verified sources.

To summarize, by trusting a scam like "McAfee - A Virus Has Been Found On Your PC!" – users can experience system infections, severe privacy issues, financial losses, and even identity theft.

We have investigated thousands of online scams; "Your NordVPN AntiVirus License Has Expired!", "Avira Security scam", "Aura Antivirus Protection", and "McAfee - TROJAN_2022 And Other Viruses Detected" just some examples of ones akin to "McAfee - A Virus Has Been Found On Your PC!".

There are various schemes on the Web; some warn of viruses/threats and urge to download/install apps or call fake helplines, others – promise prizes for taking surveys/ registering accounts, and so forth. However, the sole goal of scams is to profit from victims.

Due to how widespread deceptive and malicious content is online, we highly recommend exercising caution while browsing.

How did I open a scam website?

Scam sites are seldom accessed intentionally. A redirect to such a page can occur on a website that uses rogue advertising networks – immediately upon access or when hosted content is interacted with (e.g., clicking buttons, links, text input fields, etc.).

Online scams are also promoted by intrusive advertisements and spam browser notifications. Mistyping a site's URL can result in a redirect (or a redirection chain leading) to a deceptive webpage as well. Additionally, scam pages are promoted by adware – either through displayed ads or generated redirects.

How to avoid visiting scam websites?

Deceptive websites are primarily accessed via redirects caused by sites employing rogue advertising networks, misspelled URLs, spam browser notifications, intrusive adverts, and installed adware.

Therefore, we strongly recommend being vigilant while browsing since fake/malicious online content usually appears legitimate. For example, intrusive ads may look innocuous yet redirect to highly questionable websites (e.g., scam-promoting, gambling, pornography, adult dating, etc.).

We advise against using sites that offer pirated programs/media or other questionable services (e.g., Torrenting, illegal streaming/downloading, etc.) – since they are usually monetized via rogue advertising networks. Furthermore, it is important to pay attention to URLs and enter them with care.

To avoid receiving unwanted browser notifications – do not permit suspicious webpages to deliver them (i.e., "Allow", "Allow Notifications", etc.). Instead, deny notification requests (i.e., select "Block", "Block Notifications", etc.) or ignore them altogether.

We also advise downloading only from official/trustworthy channels and approaching installation processes with due diligence (e.g., reading terms, exploring options, using "Custom/Advanced" settings, etc.) – to prevent bundled/harmful content from infiltrating the device.

If your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate all threats.
