"YOUR COMPUTER HAS BEEN BLOCKED" removal instructions
What is "YOUR COMPUTER HAS BEEN BLOCKED"?
The "YOUR COMPUTER HAS BEEN BLOCKED" message states that the computer has been infected with various viruses/malware and that private data (Facebook Login, Credit Card Details, Email Account Login, etc.) has been stolen. The message encourages users to contact technical support via a telephone number provided. Users are often tricked into believing that this message is legitimate, however, it is a scam. This virus is very similar to the previously-distributed scam, "Your Browser Has Been Blocked".
"YOUR COMPUTER HAS BEEN BLOCKED" is promoted via various adware-type applications. These apps often claim to provide a number of 'valuable features' in order to trick users to install. After system infiltration, adware generates various intrusive advertisements (for example, banners, pop-ups, coupons, interstitial, search, and other similar ads) that often conceal underlying content of visited websites, thereby significantly diminishing the web browsing experience. In addition, some lead to malicious sites that contain infectious content - clicking them is risky and might cause further computer infections. Furthermore, adware-type applications gather various data that might be personally identifiable, including IP addresses, website URLs visited, pages viewed, search queries, geo-location, language, browser/operating system types, etc. The information is shared with cooperating third party companies who misuse personally identifiable details to generate revenue. Thus, the presence of data-tracking apps on your system can lead to serious privacy issues or even identity theft. "YOUR COMPUTER HAS BEEN BLOCKED" pop-up is a scam and, therefore, if you encounter this error message, uninstall all recently-installed and/or suspicious applications immediately.

Adware-type applications have similar characteristics. All claim to enhance the web browsing experience in some way, however, these claims are merely attempts to give the impression of legitimate software. In fact, all adware is designed to generate revenue for the developers - they deliver no value for regular users. Rather than enabling the functions promised, potentially unwanted adware-type programs cause unwanted browser redirects (thereby generating traffic for certain sites), gather personally identifiable information (which is later sold to third parties), and deliver intrusive online advertisements (using the 'Pay Per Click’ [PPC] advertising model).
How did adware-type applications install on my computer?
Most adware is distributed using a deceptive software marketing method called 'bundling'. Developers know that many users do not express enough caution when downloading and installing software. Aware of this, developers conceal bogus programs within the 'Custom/Advanced' download or installation section. By rushing and skipping steps, users expose their systems to risk of various infections and compromise their privacy.
How to avoid installation of potentially unwanted applications?
There are two main steps you should take to prevent this situation. Firstly, never rush when downloading and installing software - select the 'Custom/Advanced' settings and closely analyze each step. Secondly, decline offers to download/install third party applications and opt-out of those already included. Bundled software is often dubious and, thus, should never be installed.
