The most disturbing cyber threat you may ever come across online is a Ransomware-based virus. These malicious programs are considered to be the most dangerous viruses ever created. In this article we will be discussing one of them – .Mrcr1 File Virus. What this type of malware usually does is it penetrates your system, detects the files you cherish most and encrypts them all. Then you will be required to pay ransom to bring them back. This is a perfect example of harassment and we are going to give you all the corresponding details below. Ransomware is a type of malware, the main expertise of which is asking for ransom in exchange for undoing what it has done to your PC. This usually comes with a ransom note named your_files_are_dead.hta. There are various types of Ransomware which we are going to elaborate on in the next paragraph. What you should know is that it is generally extremely hard to remove such a program and undo whatever negative thing it has done to your computer. Even experts might find it awfully difficult to deal with the consequences of such malware.

Types of Ransomware. Where does .Mrcr1 belong?

The functions of the Ransomware-based viruses entirely depend on their subtype. Here they come with all the corresponding explanation:

  • Mobile Ransomware viruses – the ones that attack your smartphones and tablets and are known to lock the screen of these devices. Then they demand ransom in order to unlock it.
  • Monitor-locking Ransomware viruses – the ones that could only affect your computer or laptop screen in the same way as the mobile Ransomware – by making the desktop unavailable, until you pay a ransom to access it again.
  • Authority-exploited Ransomware – sometimes certain authorities may use such viruses to make some criminals pay fines or taxes. So, basically, this type is not evil, but functions in a similar way.
  • The most famous fileencrypting Ransomware subgroup – the malware versions in this subtype are the most commonly spread. These programs are probably the worst type of Ransomware, as they infect your PC, determine which files you will miss most (the ones that you commonly use); and make them inaccessible to you. After that you are harassed into paying a ransom amount in order to decrypt them. .Mrcr1 belongs to this subgroup and acts in this way as we have already mentioned in the opening paragraph.

How could you catch such an awful threat?

Sadly, you can never be sure how exactly you have encountered such a disturbing virus as .Mrcr1. There are endless possibilities: contagious web pages, torrents, shareware, and streaming websites. The most common among them are the so-called fake ads (the product of the process named Malvertising), which represent pop-up and other online ads that are programmed to redirect you to contagious online locations. As soon as you click on such an ad, you get infected with the virus. Another possible source is the fake system update requests. Sometimes some suspicious update requests appear on your monitor and they do not come from your OS, they are simply pop-ups , working in the same way as the fake ads – once clicked on, they sneak the virus inside your PC. Also, usually spam emails and their attachments could contain Ransomware (even accompanied by Trojans in some cases) and immediately after you open such a letter or its attachments, your computer may get contaminated.

What you could do next if you get the Ransom-demanding notification

We must say, in the general case the odds are not in your favor. Such cunning viruses as .Mrcr1 are extremely hazardous, partly because the infection is usually invisible up until the notification appears; and after getting the message, it becomes too late. We just need to tell you that paying the ransom has never been a good idea. This should be your last option only in case nothing else really works. You can always ask someone involved in this industry for help – people have certain knowledge and experience and might know how to remove such a virus and return your files to you. Also, you may need to do a little research and download a powerful tool against such malware. It could be paid, but it is still better to spend your money on that, and not on agreeing with the hacker’s demands. What we recommend most is to follow the steps described below this article. The Removal Guide there should be what you need to remove the contamination. It will also attempt to restore at least some of your afected files, however we cannot promise success in this. But it is worth a try.
