What is Access to this pc has been blocked for security reasons scam?

There are many deceptive websites designed to look like official Microsoft (or other company's) pages and display fake virus and (or) error notifications with telephone numbers. Websites of this type are called technical support scams. Scammers behind these pages attempt to trick users into paying money for unnecessary services, programs or providing remote access to their computers.

Access to this pc has been blocked for security reasons scam in detail

This particular technical support scam website displays a fake virus notification ("Windows Firewall Protection Alert") claiming that access to a computer has been blocked due to detected spyware ("Pornographic Spyware"). It encourages visitors to call the +1-866-237-6010 number to solve the occurred problem/remove the detected threat.

It is worth mentioning that this page displays a fake Windows Security window, runs a fake virus scan, and displays a couple of other pop-up windows disguised as system notifications about detected threats. As stated in those pop-ups, detected malware can steal email and Facebook passwords, financial information, personal documents, images, and other files.

The main purpose of this scam website is to trick visitors into calling the provided number as soon as possible. Usually, scammers behind websites of this type attempt to trick visitors into paying money for fake, unnecessary services, programs or providing a remote access to their computers.

It is important to mention that scammers could use the provided remote access to steal personal information (for example, credit card details, login credentials), commit identity fraud, download sensitive files, install malware, and so on. Therefore, it is strongly recommended to ignore websites of this type and never call telephone numbers displayed on them.

It is worthwhile to mention that users do not visit technical support scam websites intentionally. Typically, these pages are promoted through deceptive advertisements, other shady pages, and potentially unwanted applications (PUAs).

More about PUAs

PUAs can be designed to serve advertisements, for example, coupons, banners, surveys, pop-up ads. Those ads can be used to advertise shady websites or designed to download or even install unwanted apps by running certain scripts.

Also, PUAs can be designed to gather Internet Protocol addresses, geolocations, URLs of visited pages, entered search queries, etc., or even sensitive information. What is worse, data collected by installed PUA could be shared with third parties (potentially cybercriminals), used to steal identities, online accounts, etc.

Technical support scams in general

Most technical support websites use scare tactics to trick unsuspecting visitors into calling the provided number. As a rule, scammers behind these pages attempt to extract money or get remote access to computers.

There are many examples of technical support pages. Some of them are "Code 0x03A10 (0E10)", "Firewall Spyware Alert", and "McAfee Tollfree". It is common for these pages to look like official websites of various software companies like Microsoft and Apple.

In most cases, users download or install potentially unwanted applications when they finish downloading or installing other programs without changing certain settings and options. Typically, downloaders, installers that have PUAs included in them as additional offers also have "Custom", "Manual", "Advanced" or other settings, or ticked checkboxes that can be used to decline unwanted offers.

In other cases, users cause unexpected downloads, installations by clicking deceptive advertisements designed to run certain scripts. As a rule, ads that can cause downloads, installations appear on questionable, potentially malicious websites.

How to avoid installation of potentially unwanted applications?

Questionable sources, channels like third-party downloaders, installers, Peer-to-Peer networks (for example, torrent clients, eMule), unofficial websites, etc., should not be used to download or install any programs. It is common for those channels to be used as tools to distribute unwanted software.

Advertisements on shady pages should not be clicked - they can be designed to open other unreliable websites or even download, install unwanted software. Downloaders and installers that have settings like "Custom", "Advanced", or some ticked checkboxes should be checked for offers to download or install unwanted applications.

Suspicious plug-ins, add-ons, extensions installed on a browser, and programs of this kind that installed on the operating system should be removed. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
