"Windows Was Blocked Due To Questionable Activity" removal instructions
What is "Windows Was Blocked Due To Questionable Activity"?
"Windows Was Blocked Due To Questionable Activity" is yet another scam message used to extort money from unsuspecting users. Delivered by deceptive websites, the message states that the system has been blocked and encourages users to immediately contact 'tech support' via a telephone number provided. In fact, these claims are false and you should never call this number. Furthermore, redirects to websites that deliver the "Windows Was Blocked Due To Questionable Activity" message might indicate the presence of potentially unwanted applications (PUAs) on the system.
This scam message states that Windows Operating System has been blocked and that users must contact tech support (via the "+1-877-640-1433" telephone number) to restore everything. Once contacted, these people will ask users to pay a certain sum of money for assistance (this is not even required, since the "Windows Was Blocked Due To Questionable Activity" error is fake). You should leave the website that displays this scam immediately. Be aware that these sites are often designed to prevent users from closing browser tabs/windows. In this case, terminate the browser process using Windows Task Manager. Do not restore the previous browser session the next time you run the browser, since this will reopen the rogue site.
Websites that deliver fake error messages are often opened by PUAs. Therefore, these redirects can indicate the presence of rogue apps. As well as causing redirects, PUAs are also likely to deliver coupons, banners, pop-ups, and other similar advertisements that can lead to dubious websites and even execute scripts that download/install other PUAs. Therefore, clicking them can result in various system infections. Additionally, intrusive ads are delivered using tools that enable placement of third party graphical content on any site. Therefore, they often conceal underlying content, thereby significantly diminishing the browsing experience. Another important issue is information tracking. PUAs usually gather IP addresses, website URLs visited, web pages viewed, search queries, and other similar data relating to browsing activity. Collected data (IP addresses, website URLs visited, pages viewed, search queries, etc.) often includes personal details that developers sell to third parties (potentially, cyber criminals). These people misuse private data to generate even more revenue. Thus, information tracking can lead to serious privacy issues or even identity theft. These applications should be uninstalled immediately.

To eliminate Windows Was Blocked Due To Questionable Activity virus our malware researchers recommend scanning your computer with Spyhunter.
"Windows Was Blocked Due To Questionable Activity" shares many similarities with dozens of other scam errors, such as "Microsoft Detected Malicious Virus And Blocked Your Computer", "Hard Drive Safety Delete", and "Error # 0x80092ee9". These scams often claim that the system is infected, not activated, missing files, or damaged in other similar ways, just to trick users into calling fake 'tech support' or downloading various unwanted applications (e.g., system cleaners). In any case, never trust these messages and, if you have already downloaded any of the promoted applications, remove them immediately.
How did potentially unwanted applications install on my computer?
Some PUAs have official download websites, however, most are proliferated using intrusive advertisements and a deceptive marketing method called "bundling" (stealth installation of third party applications together with regular software). Developers hide "bundled" apps behind "Custom/Advanced" settings (or other sections) of the download/installation processes. Furthermore, many users often rush these procedures and skip steps. Additionally, they click various advertisements without understanding the possible consequences. This behavior often leads to inadvertent installation of third party applications. In this way, users expose their systems to risk of various infections and compromise their privacy.
How to avoid installation of potentially unwanted applications?
To prevent this situation, be very cautious when browsing the Internet and downloading/installing software. Bear in mind that intrusive advertisements typically seem legitimate, since developers invest many resources into intrusive ad design. In fact, they usually redirect to dubious websites (gambling, adult dating, pornography, survey, and similar). If you encounter these ads, remove all suspicious applications and browser plug-ins immediately. Furthermore, download programs from official sources only, preferably using direct download links. Third party downloaders/installers often include rogue apps, and thus such tools should never be used. Study each window of the download/installation dialogs using the "Custom" or "Advanced" settings. Opt-out of additionally-included apps and decline offers to download/install them. The key to computer safety is caution. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
