Microsoft Has Detected A Porn Virus Scam
Written by Tomas Meskauskas on (updated)
What is Microsoft Has Detected A Porn Virus?
"Microsoft Has Detected A Porn Virus" is a deceptive pop-up error message claiming that the system has been infected. This error is displayed by a malicious website, which users often visit inadvertently - they are automatically redirected to it by various potentially unwanted programs (PUPs).
These applications usually infiltrate systems without users' consent ("bundling" method). As well as causing unwanted redirects, PUPs deliver intrusive online advertisements and continually track Internet browsing activity.
"Microsoft Has Detected A Porn Virus" states that a computer infection has been detected and that private information (logins/passwords, credit card details, etc.) is at risk. According to the pop-up, the malware must be removed immediately by contacting technical support via a toll-free telephone number ("+1-844-786-8921").
Certified technicians then (supposedly) safely remove the malware. In fact, the "Microsoft Has Detected A Porn Virus" error is fake and should not be trusted. By falsely stating that the system is infected, cyber criminals attempt to trick users into calling and paying for services that are not required. Therefore, never attempt to contact these people.
You can remove this error by simply closing the web browser. Be aware that PUPs employ a "virtual layer" to generate pop-up, coupon, banner, and other similar advertisements. The virtual layer enables placement of third party graphical content on any site.
Therefore, displayed ads often conceal underlying content, thereby significantly diminishing the Internet browsing experience. In addition, they often redirect to malicious websites and even accidental clicks can result in high-risk adware or malware infections. Another downside is information tracking.
Research shows that potentially unwanted programs gather Internet Protocol (IP) addresses, geo-locations, mouse/keyboard activity, URLs visited, pages viewed, queries entered into search engines, and other similar information relating to users' Internet browsing activity.
This collected data might contain personal details that developers of PUPs share with third parties. There is a high probability that private details are misused to generate revenue. This behavior can lead to serious privacy issues or even identity theft. PUPs should be uninstalled immediately from your system.

The Internet is full of websites displaying fake errors similar to "Microsoft Has Detected A Porn Virus". Examples include System Blocked For Security Reasons, Your System Might Be Infected, Do Not Ignore This Windows Alert, and many others. All claim that the system is missing files or damaged in other similar ways, however, these errors should never be trusted.
They are merely attempts to generate revenue by extorting money from unsuspecting users. Potentially unwanted programs are designed only to generate revenue for the developers.
By delivering promises to enable various 'useful functionality', they attempt to give the impression of legitimacy, however, rather than providing any significant value for regular users, PUPs cause unwanted browser redirects, deliver intrusive ads, and collect private information.
How did adware install on my computer?
Cyber criminals proliferate potentially unwanted programs using a deceptive marketing method called "bundling" - stealth installation of third party applications with regular software. Developers know that most users rush the download and installation processes and skip many steps.
Therefore, bundled programs are hidden within the "Custom/Advanced" settings. Skipping this section often leads to inadvertent installation of potentially unwanted programs.
How to avoid installation of potentially unwanted applications?
PUPs are distributed using the bundling method. Therefore, never rush the download or installation processes. Select the "Custom/Advanced" settings and carefully analyze each step. Furthermore, opt-out of all additionally-included programs and decline offers to download/install them.
