What is the "Your Windows 10 is infected with viruses" pop-up?

During a routine inspection of rogue websites, our researchers discovered the masterofkeeps[.]xyz website, which in turn resulted in us learning of the "Your Windows 10 is infected with viruses" scam. This scheme makes false claims about visitors' devices being infected in order to gain and subsequently abuse users' trust. Typically, such scams are used to endorse untrustworthy/harmful software and/or obtain funds through fraud.

It must be emphasized that while "Your Windows 10 is infected with viruses" employs the names of genuine products/companies, it is in no way associated with either the Microsoft Corporation or McAfee Corp.

"Your Windows 10 is infected with viruses" scam overview

Deceptive content is promoted on various rogue sites. We encountered "Your Windows 10 is infected with viruses" on the masterofkeeps[.]xyz website, yet it is likely hosted by countless others.

This scam consists of multiple pop-up windows. The top-most pop-up graphically mimics Windows 10 system messages. It states that the device has been damaged by "viruses and other malicious applications". The user is encouraged to repair the damage, and it is evident that this process is to be initiated by pressing the "Renew License" button. This window also warns against closing the website.

The other pop-ups are disguised as the interface, system scan, and threat alerts displayed by the McAfee anti-virus. An interesting detail is that the fake interface mimics that of Norton anti-virus rather than McAfee.

As mentioned in the introduction, all of these claims are false. Furthermore, no site can detect threats present on a visitor's device; hence, any that claim such - are scams.

Most commonly, schemes of this kind are used to endorse fake anti-virus tools, browser hijackers, adware, and various PUAs (Potentially Unwanted Applications). This content can be presented as or bundled with a legitimate product (e.g., McAfee, Norton, etc.).

Sometimes, such scams can redirect to the official download webpages of genuine software - however, this promotion is done without the developers' approval. Scammers often use deceptive/questionable means to push content, thus abusing the affiliate programs to acquire illegitimate commissions.

Alternatively, these scams may request users to make payments, e.g., activate software, register an account, subscribe to a service, etc. Cyber criminals may ask victims to pay through payment gateways that operate as phishing websites or in difficult/impossible to trace methods (e.g., cash hidden in packages, cryptocurrencies, gift cards, etc.).

To summarize, by trusting the "Your Windows 10 is infected with viruses" scam, users can experience system infections, severe privacy issues, financial losses, and even identity theft.

The Internet is rife with deceptive and malicious content. Due to how widespread scams are online, we strongly advise exercising caution when browsing.

How did I open a scam website?

Scams are often promoted by spam browser notifications and intrusive advertisements. Deceptive webpages can also be accessed through mistyped URLs. Sites that use rogue advertising networks commonly cause redirects to scam pages the moment they are entered or when buttons, links, ads, or other hosted content is clicked. Adware endorses online scams as well. This software can display adverts promoting such websites or force-open them.

How to avoid visiting scam websites?

We advise against visiting sites offering illegal or questionable services (e.g., Torrenting, pirated content streaming/viewing, etc.) since they typically use rogue advertising networks, which often push scams.

Spam browser notifications are also used to promote deceptive content. Therefore, do not press "Allow", "Allow Notifications", or similar options presented by questionable sites. Instead, we recommend ignoring or denying notification delivery requests (i.e., clicking "Block", "Block Notifications", etc.).

Furthermore, to avoid installing adware (which is known to endorse online scams), it is important to download only from official/verified channels. When installing, we advise reading terms, studying possible options, using the "Custom/Advanced" settings, and opting-out of all additions - to prevent allowing bundled adware into the system.

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