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 support'. They attempt to trick people into believing that their computers are infected/blocked and to make contact via the telephone number provided. Most people do not open websites of this type intentionally - they are forced to visit them by potentially unwanted apps (PUAs) installed on their systems. These apps usually cause unwanted redirects, deliver advertisements, and record information.

This is a VIRUS. Your computer is blocked file scam

This deceptive website is capable of turning on full-screen mode. Once opened, it displays a fake virus alert pop-up window stating that the visitor's computer is blocked. According to the pop-up, this happened, since the Windows registration key is illegal, the Windows system is hacked and used from an undefined location, there are pirated programs installed on the system, or it is proliferating viruses over the internet. To solve the problem and unblock their computers, visitors are encouraged to contact "Microsoft Helpline/Microsoft Security" by calling the "+1-800-278-6064" number. Furthermore, this deceptive website triggers pop-up windows that encourage users to save or open dubious (HTML) files. It is likely that by agreeing to do so, people will force the browser to crash. Do not to trust this scam and and close the window. If possible, do this in the usual way, otherwise, use Task Manager and end the browser process from there. Note that the closed session should not be restored. Additionally, if some of the aforementioned files were downloaded, they should be deleted immediately.

PUAs that often lead to these websites usually gather information relating to browsing activities. Some examples of data that they collect are IP addresses, entered search queries, URLs of visited websites, geolocations, etc. Some might also be used to gather sensitive (personal) details. People who create these apps share the data with other parties who misuse it to generate revenue. The third parties might include cyber criminals. Furthermore, installed PUAs can feed users with coupons, banners, pop-up ads, surveys, and other intrusive advertisements. These usually conceal underlying content of visited websites, which can be annoying. People who click them are usually redirected to dubious websites (such as this scam web page) or unintentionally cause unwanted download/installation of other unwanted apps.

The internet is full of 'technical support' and other scams. Other examples of other similar scams include "Windows Protected Your PC", "Hard Drive Safety Delete", and "Backdoor Virus Detected". Typically, they are used to extort money from unsuspecting people. Scammers pose as official representatives and try to trick people into believing that they must pay for technical services or software to solve the problems. Unwanted apps that lead to these scams are all very similar. Most generate revenue for their developers (and other parties) by gathering data, causing unwanted redirects, and feeding users with ads. Developers promote them as legitimate and useful apps, however, this is all part of the scam.

How did potentially unwanted applications install on my computer?

These apps are usually installed without users' knowledge - they download and install them unintentionally or accidentally when developers employ the "bundling" method. Bundling is used to trick users into downloading/installing PUAs with other, regular software. To achieve this, they hide information regarding the inclusion (bundling) of PUAs in "Custom", "Advanced" and other similar settings of software set-ups. Note that unwanted apps cannot be downloaded or installed without users' permission (even if this is given accidentally). Furthermore, many users give this permission simply by skipping software download/installation steps without checking and changing the available settings.

How to avoid installation of potentially unwanted applications?

Download all applications from reputable, official websites. Do not use third party software downloaders/installers, torrent clients, eMule (and other Peer-to-Peer networks), unofficial websites, or other similar sources. Check all available "Advanced", "Custom" and other settings of any download or installation set-ups. Decline offers to download/install unwanted apps before completing the setup. Do not click intrusive ads displayed on dubious websites - they can lead to other, potentially malicious pages or execute scripts that download/install unwanted apps. If your browser is causing unwanted redirects, or intrusive ads appear on all visited pages, check the default browser for any unwanted extensions, plug-ins, or add-ons installed. Remove unwanted entries immediately. Also check the list of programs installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
