"Windows Error Code: DLL011150" scam removal instructions
What is the "Windows Error Code: DLL011150" scam?
"Windows Error Code: DLL011150" refers to a technical support scam, run on various deceptive websites. This scheme claims that it is a "virus alert" from Microsoft, informing users that their devices have been supposedly blocked - due to suspicious activity detected on them. It must be emphasized that all of the information provided by "Windows Error Code: DLL011150" is false and this scam is in no associated with the Microsoft Corporation. Users rarely access sites that promote scams intentionally, most enter them through mistyped URLs, are redirected to them by intrusive advertisements or by PUAs (Potentially Unwanted Applications). These apps do no need to express user permission to be installed onto systems. PUAs are designed to cause redirects, run intrusive advertisement campaigns, hijack browsers and collect browsing-related information.
Once a site running "Windows Error Code: DLL011150" is accessed, visitors are presented with a pop-up window - the text presented in which is read aloud. The scheme states that it is a "virus alert from Microsoft" and that the users' computers have been blocked. According to the pop-up, the device was allegedly locked due to suspicious activity detected on the user's IP (Internet Protocol) address, which in turn was caused by a nonexistent system infection. The scam then lists fake issues already present in the device and urges visitors to contact text support experts via provided telephone number. Despite the fraudulent helplines being presented as toll-free, they are frequently very expensive. Typically, scammers attempt to gain access to the computers of potential victims, pretend to fix the nonexistent problems and ask for exorbitant fees for their "services". In the best case scenarios, victims devices are left unharmed. However, more commonly scammers remove any legitimate anti-viruses, install and/or trick users into purchasing fake ones, infect the devices with malware and extract personal/financial information. The malicious software they install can be trojans, ransomware, cryptominers and various other malignant programs. Scammers often infect their victims' machines with RATs (Remote Access Trojans), to ensure indefinite access and control over the computers - without their owners' knowledge. Additionally, scammers request users to provide vulnerable information, e.g. names, surnames, addresses, emails, banking account and/or credit card details. Instead of outright asking for such data, scammers may ask users to enter it into phishing websites, which are disguised and/or function as payment gateways. The preferred payment methods for the "services rendered" typically deal with digital currencies (e.g. pre-paid vouchers, gift-cards, cryptocurrencies, etc.), due to the fact that they are difficult/impossible to trace. What is more, scammers usually target victims repeatedly, if their initial scam attempts are successful. To summarize, trusting the "Windows Error Code: DLL011150" scheme can result in system infections, financial losses, severe privacy issues and identity theft.
As mentioned in the introduction, one of the main culprits behind rogue redirects to deceptive/scam pages are PUAs. These applications can have various abilities in varied combinations, aside from force-opening harmful websites. Adware-types deliver intrusive ads, which seriously diminish the browsing experience. When clicked on, the delivered adverts redirect to unreliable/dangerous sites and some can even stealthily download/install software. Browser hijacker type PUAs modify browser settings and restrict access to them - in order to promote fake search engines. The promoted web searching tools are seldom able to generate search results, so they redirect to Google, Yahoo, Bing and other legitimate search engines. Most PUAs (regardless of type) have data tracking abilities. They can record browsing activity (browsing and search engine histories) and collect personal information extracted from it (IP addresses, geolocations and other details). The gathered data is then shared with and/or sold to third parties (potentially, cyber criminals). Therefore, to ensure device integrity and user safety - all suspicious applications and browser extensions/plug-ins must be removed without delay.

"Your Computer Is In Blocked State", "Error MS-77X1", "Covid19 Warning Alert", "Windows Alert & Warning" - are some examples of other tech support scams. The Internet is rife with various schemes. Popular scam models include (but are not limited to): warnings that the system is infected or at risk, alerts that a crucial piece of software is outdated or missing, prize giveaways and raffles, ludicrous offers and deals, etc. Regardless of what scams claim, offer, request or demand, the end-goal is the same - to generate revenue for the scammers / cyber criminals behind them.
How did potentially unwanted applications install on my computer?
PUAs are proliferated via download/installation setups of other products. This deceptive marketing technique of pre-packing regular software with unwanted or malicious additions - is called "bundling". Rushed downloads/installations (e.g. ignored terms, used "Quick/Express" settings, etc.) - increase the risk of unintentionally allowing bundled content into the system. Select PUAs have "official" download webpages. Once clicked on, intrusive adverts can execute scripts to download/install PUAs without user consent.
How to avoid installation of potentially unwanted applications?
It is recommended to research products before download/installation and/or purchase. Only official and verified download channels must be used. Since untrustworthy sources, e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders - often offer deceptive and/or bundled content. When downloading/installing, it is advised to read terms, explore all possible options, use the "Custom" or "Advanced" settings and opt-out from additional apps, tools, features, etc. It is just as important to exercise caution when browsing. Intrusive advertisements appear legitimate, however they redirect to highly questionable sites (e.g. gambling, pornography, adult-dating, and so on). In case of encounters with ads and/or redirects of this kind, the system must be inspected and all suspect applications and browser extensions/plug-ins - immediately removed from it. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
