"This is a VIRUS. Your computer is blocked file" removal instructions
What is "This is a VIRUS. Your computer is blocked file"?
"This is a VIRUS. Your computer is blocked file" is another technical support scam used by cyber criminals who claim to offer legitimate technical service. They attempt to trick people into thinking that their computers are infected/blocked and contacting them via the provided telephone number. Most people do not open websites of this type intentionally, they are forced to visit them by installed potentially unwanted apps (PUAs). These apps usually cause unwanted redirects, deliver advertisements and record information.
This deceptive website is capable of turning itself into full-screen mode. Once opened, it displays a fake virus alert pop-up window saying that visitor's computer is blocked. According to this pop-up, it happened because Windows registration key is illegal, Windows system is hacked and used from undefined location, there are some pirated programs installed on it or the system is spreading viruses over the Internet. In order to solve the occurred problem/unblock computers, visitors are encouraged to contact "Microsoft Helpline/Microsoft Security" by calling the "+1-800-278-6064" number. Besides, this deceptive website triggers pop-up windows offering users to save or open some questionable (HTML) files. It is very likely that by agreeing to do so people would force a browser to crash. We strongly recommend not to trust this scam and to close it, if it is possible to do it in a normal way. If not, then we recommend to use Task Manager and end the browser's process from there, however, closed session should not be restored. Additionally, if some of the aforementioned files were downloaded, they should be deleted.
PUAs that often lead to such websites usually gather information related to user's browsing activities too. Some examples of data that they collect are: IP addresses, entered search queries, URLs of visited websites, geolocations etc., however, some of them might be used to gather sensitive (personal) details too. People who create these apps share recorded data with other parties who misuse it to generate revenue. Third parties might include cyber criminals too. Furthermore, installed PUAs might be feeding their users with various coupons, banners, pop-up ads, surveys and other intrusive advertisements. These ads usually conceal contents of visited websites which can be really annoying. People who click them usually get redirected to unreliable websites (like this scam page) or unintentionally cause unwanted downloads/installations of some other unwanted apps.

To eliminate This is a VIRUS. Your computer is blocked file virus our malware researchers recommend scanning your computer with Spyhunter.
The Internet is full of various technical support and other scams, here are couple examples of other similar scams: "Windows Protected Your PC", "Hard Drive Safety Delete" and "Backdoor Virus Detected". Typically, they are used to extract money from unsuspecting people. Scammers disguise themselves as official representatives and try to trick people into thinking that they need to pay for some technical services or software to solve the occurred problems. Unwanted apps that lead to these scams are also very similar. Most of them are designed to generate revenue for their developers (and other parties) by gathering data, causing unwanted redirects and feeding users with ads. Their developers promote them as legitimate (and also useful) apps, however, most of the times these are just false promotions.
How did potentially unwanted applications install on my computer?
Apps of this type usually get installed without users being aware of that. They download and install them unintentionally/accidentally. It happens when other people who develop these apps use the "bundling" method, they use it to trick users into downloading/installing PUAs within some other, desired software. To achieve this, they hide these apps (information about them being included/bundled) in "Custom", "Advanced" and other similar settings of software's setups. One way or another, unwanted apps cannot be downloaded and installed without user's permission (even if it is given accidentally). There are many users who allow it by simply skipping software download/installation steps without checking (and changing) available settings.
How to avoid installation of potentially unwanted applications?
We advise to download all applications from reliable, official websites. What we do not recommend, is to use various third party software downloaders/installers, torrent clients, eMule (and other Peer-to-Peer networks), unofficial websites or any other similar sources for that. Furthermore, all available "Advanced", "Custom" and other settings of any download or installation setups should not be left unchecked. In other words, any offers to download/install unwanted apps should be dismissed before completing the setup. Various intrusive ads that are displayed on questionable websites should not be clicked too. They lead to other, potentially malicious pages or execute scripts that download/install unwanted apps. If a browser is causing unwanted redirects and/or intrusive ads appear on all visited pages, then we recommend to check the default web browser and to see if there are any unwanted extensions, plug-ins or add-ons installed on it. If yes, then they should be removed as soon as possible. We also recommend to check the list of programs that are installed on the operating system itself too. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
