What is Microsoft Corporation HAS BLOCKED YOUR PC?
Similar to High Priority Message, Warning! Malware Detected!, Your Computer May Have a Virus!, and many others, "Microsoft Corporation HAS BLOCKED YOUR PC" is a fake error message displayed by a malicious website. Users often visit this site inadvertently - they are redirected by various potentially unwanted programs (PUPs) that infiltrate systems without permission.
As well as causing redirects, PUPs deliver intrusive advertisements and continually monitor users' Internet browsing activity.
This error states that the system is infected and, therefore, Microsoft Corporation has blocked access. It is also stated that users' personal details (banking details, logins/passwords, stored photos, etc.) are at risk, and that the malware must be eliminated immediately by contacting "Microsoft technicians" via a telephone number ("1-866-216-1642") provided.
These self-proclaimed technicians then supposedly guide victims through the malware removal process. Bear in mind, however, that "Microsoft Corporation HAS BLOCKED YOUR PC" is a scam and has nothing to do with Microsoft.
Cyber criminals attempt to generate revenue by tricking users into believing that the system is infected and paying for technical support that is not required. This error message should be ignored - it can be removed simply by closing the web browser. Be aware that PUPs display intrusive ads via tools that enable placement of third party graphical content on any site.
Therefore, pop-ups, banners, coupons, and other intrusive ads often conceal visited website content, thus diminishing the browsing experience. Some execute scripts designed to download and install malware. Therefore, clicking them might cause further computer infections.
PUPs track users' Internet browsing activity by recording IP addresses, website URLs visited, pages viewed, search queries, and other similar information.
The data might contain personal details that PUP developers share with third parties to generate revenue (the third parties also generate revenue by misusing users' private details). Therefore, the presence of data-tracking apps can lead to serious privacy issues or even identity theft. Uninstall all PUPs immediately.

As mentioned above, Microsoft Corporation HAS BLOCKED YOUR PC shares many similarities with dozens of other fake errors. All claim that the system is damaged (for example, infected, missing files, etc.), however, they are designed only to trick unsuspecting users into purchasing unnecessary services.
Research shows that all PUPs are virtually identical. Many claim to provide various "useful features", and yet, deliver no value for regular users - claims to provide this functionality are merely attempts to give the impression of legitimacy.
PUPs cause unwanted redirects (thereby promoting dubious websites), deliver intrusive advertisements (via the "Pay Per Click" advertising model), and gather user-system information.
How did adware install on my computer?
Some PUPs have official download websites, however, criminals proliferate them using a deceptive marketing method called "bundling", and via the aforementioned ads. Therefore, users often install PUPs inadvertently, or these programs simply infiltrate systems without consent.
Bundling is stealth installation of third party apps together with regular (usually free) software. Developers hide bundled apps within the "Custom" or "Advanced" settings of the download/installation processes. Many users skip download/installation steps and click various ads, thus exposing their systems to risk of various infections and compromising their privacy.
How to avoid installation of potentially unwanted applications?
The main reasons for computer infections are poor knowledge and careless behavior. The key to computer safety is caution. Therefore, be very careful when browsing the Internet and when downloading/installing software. Never click ads displayed online. Many intrusive ads seem genuine, but no matter how tempting they may appear, do not take the risk of clicking them.
Furthermore, closely analyze each download/installation step (especially the "Custom/Advanced" settings) and opt-out of all additionally-included programs. Download your software from trusted sources only. Select a direct download URL rather than using third party downloaders/installers, since most of these tools bundle PUPs.
