"Windows firewall has blocked some features of this program" scam removal instructions
What is the "Windows firewall has blocked some features of this program" scam?
"Windows firewall has blocked some features of this program" is a deceptive pop-up window displayed by untrustworthy websites. It is disguised as a genuine Windows error message. The purpose of this scam is to trick users into calling an illegitimate technical support helpline. Trusting this fake alert can lead to financial loss, severe privacy issues, system infections and various other serious problems. Few visitors access sites promoting scams like this one - intentionally, most get redirected to them by intrusive adverts or by PUAs (Potentially Unwanted Applications). These apps do not need express user permission to be installed onto the system.
This fake pop-up window is presented as a "Windows Security Alert", informing users that supposedly the Windows Firewall has disabled certain features of a program. Specifically, this program has been blocked from accepting incoming network connections. Should this piece of software be unblocked, it will be likewise unblocked on all public networks that users connect to. The pop-up also shows the alleged name, publisher and location of this program. Additionally, it contains buttons to either keep blocking the nonexistent program or to unblock it. The fake alert urges users to call a "tech support" helpline. It must be emphasized that "Windows firewall has blocked some features of this program" is not a legitimate alert and all of the information presented in it is false. Typically, the telephone numbers provided by such scams are expensive, and the scammers behind them - generate profit by tricking users into staying on the line for as long as possible. These criminals may attempt to gain access and control over the users' devices by claiming to offer remote technical support services. They can infect the system with trojans, ransomware and other malware as well. In some cases, scammers also try to extract users' personal information, e.g. names, addresses, emails, banking account and credit card details, etc. To summarize, trusting the "Windows firewall has blocked some features of this program" scam poses a danger to device and user safety.
Aside from force-opening deceptive/scam pages, PUAs can cause redirects to sale-oriented/promotional, rogue, compromised and malicious websites. However, these applications can have other/additional abilities. Adware-types can deliver pop-ups, banners, coupons, surveys and other intrusive advertisements. They diminish the browsing experience and upon being clicked - redirect to similarly dangerous sites and some can stealthily download/install undesirable software. Other types of PUAs, classified as browser hijackers - modify browsers in order to promote fake search engines, and they can limit/deny access to the browser's settings. Illegitimate web searchers are usually unable to provide search results, so they redirect to Yahoo, Bing, Google and other genuine ones. Most PUAs can track data. They can monitor browsing activity (browsing and search engine histories) and gather personal information extracted from it (IP addresses, geolocations and other details). The collected data is often shared with third parties, seeking to misuse it for profit - potentially, by putting it to criminal use. To protect device integrity and user safety, all suspicious applications and browser extensions/plug-ins must be eliminated immediately upon detection.

"WIN.DLL011150 Error", "Your Windows 10 is infected with 5 viruses!" and "Attention 22 threats found" are a few examples of other technical support scams. The Web is full of various schemes that make likewise varied claims. The purpose may be to push users into: calling fake tech support/service lines; allowing unauthorized access to their devices; downloading/installing and/or purchasing nonoperational, untrustworthy and malicious software; making monetary transactions (e.g. fake shipping, registration, subscription and other payments); revealing personal and sensitive information, and so on. Regardless of what scams claim, request or demand, their end-goal is the same - to generate revenue for the scammers / cyber criminals behind them.
How did potentially unwanted applications install on my computer?
Some PUAs have "official" promotional (download) webpages, which are often promoted by scam sites. These applications can also be downloaded/installed together with other software. This false marketing technique of pre-packing ordinary products with unwanted or malicious additions - is called "bundling". By rushing through download/installation processes (e.g. by ignoring terms, skipping steps, etc.) - users risk inadvertently allowing bundled content into their devices. Intrusive ads can infiltrate these apps into systems as well. Upon being clicked, they can execute scripts to make stealthy downloads/installations.
How to avoid installation of potentially unwanted applications?
It is recommended to research products before download/installation and/or purchase. All downloads must be done from official and verified sources. Unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders - can offer deceptive and bundled content; therefore, they are considered to be untrustworthy. When downloading/installing, it is important to read terms, explore all available options, use the "Custom" or "Advanced" settings and opt-out from additional apps, tools, features, and so on. It is advised to excercise caution when browsing. Intrusive advertisements appear legitimate, however they redirect to highly unreliable and questionable pages (e.g. gambling, pornography, adult-dating, etc.). In case of encounters with such adverts/redirects, the system must be inspected and all suspect applications and/or browser extensions/plug-ins removed without delay. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
