"WIN.DLL011150 Error" scam removal instructions
What is the "WIN.DLL011150 Error" scam?
"WIN.DLL011150 Error" is a technical support scam promoted by various deceptive websites. This scheme has been observed being run on azurewebsites.net, though not exclusively. The "WIN.DLL011150 Error" scheme claims that the computer has been blocked due to the Windows registration key supposedly being illegal and the device having been compromised. This scam attempts to trick people into exposing their registration keys and calling a fake 'tech support' number. No site can detect threats/issues present on devices - any that make such claims are scams. Users rarely access these deceptive web pages intentionally - most are redirected to them by intrusive advertisements or Potentially Unwanted Applications (PUAs) already infiltrated into the system.
The pop-up window presented on sites running the "WIN.DLL011150 Error" scam states that it is a "VIRUS ALERT TO Microsoft" with the error code specified as "WIN.DLL01150". Users are warned not to close this web page and/or restart their computers. Their devices have been allegedly blocked for security reasons, as their Windows registration key have been found to be "illegal". Additionally, a window is supposedly hacked and/or controlled from an unspecified location, and it is proliferating viruses over the internet. To regain access to their computers, users are urged to call the provided free technical support number and this instruction is repeated several times throughout the deceptive page. Furthermore, the "unusual activity" on the device can apparently pose a threat to stored data and financial activity. The scheme also instructs users to enter their Microsoft registration key to unblock their computers. Note that all of the information provided by "WIN.DLL011150 Error" is false. Technical support scams are typically used to fool users into calling fake and expensive telephone numbers. From there on, victims can be held on the line with nonsensical technobabble, while their telephone bill is racking up. Alternatively, the scammers can attempt to extort personal information (e.g. names, addresses, emails, banking account or credit card details, etc.) from users or gain access and control over their devices. Another way that scammers can abuse users' trust is by requesting payment for "services rendered". In summary, trusting the "WIN.DLL011150 Error" scam can lead to system infections, financial loss, serious privacy issues and even identity theft. In some cases, closing the deceptive web page can be impossible. In such instances, Task Manager must be used to end the browser process. When the browser is reopened, the previous process must not be restored, as the scam page will then be reopened.
As mentioned, one of the main causes of rogue redirects to untrusted/malicious websites are PUAs, however, these unwanted applications can have other capabilities. They can run ad campaigns (i.e., deliver unwanted and harmful advertisements). When clicked, these intrusive ads redirect to dubious/dangerous sites and can stealthily download/install rogue software (e.g. PUAs). Another type of PUA can modify browsers, restrict/deny access to settings, and promote fake search engines. Most PUAs have data tracking capabilities. They can record browsing activity (URLs visited, pages viewed, search queries typed, etc.) and gather personal information derived from it (IP addresses, geolocations and other details). The collected data is often monetized by sharing with third parties (potentially, cyber criminals) seeking to misuse it for profit. These unwanted apps pose a significant threat to device and user safety. Therefore, you are strongly advised to eliminate all suspect applications and browser extensions/plug-in immediately upon detection.

"System Warning Alert", "Activation Security Warning", "Attention 22 threats found" and "ZoneAlarm Global Virus Alert" are some examples of other tech support scams. The Web is rife with various deceptive/scam websites. Technical support schemes are just one type. Other popular scam models include (but are not limited to) fake prize giveaways, alerts that a piece of essential software is allegedly outdated, "unbelievable" offers/deals, and so on. Scams operate differently (they can make different requests, claims and demands), however, their purpose is identical: to generate revenue for the scammers/cyber criminals behind them.
How did potentially unwanted applications install on my computer?
PUAs are distributed via the download/installation set-ups of other software. This deceptive marketing tactic of pre-packing regular products with unwanted or malicious additions is called "bundling". Rushing downloads/installations (e.g. ignoring terms, skipping steps, using pre-set options, etc.) increases the risk of inadvertent installation of bundled content. Some PUAs have "official" download web pages. Intrusive ads proliferate these applications as well. Once clicked, they can execute scripts to download/install PUAs without users' consent.
How to avoid installation of potentially unwanted applications
You are advised to research all products before download/installation or purchase. Use only official and verified download channels. Untrusted sources such as unofficial and free file-hosting sites, Peer-to-Peer sharing networks and third party downloaders commonly offer deceptive and/or bundled content. When downloading/installing, it is important to read the terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out of additional apps, tools, features, etc. Intrusive advertisements may seem legitimate and harmless, however, they can redirect to dubious websites (e.g. gambling, pornography, adult-dating and others). If you encounter ads/redirects of this kind, check the system and immediately remove all suspicious applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
