Virus DetailsWhat is .Crab 2.0 Virus

Ransomware is a kind of malware that seeks to lock some component of your device. Normally, the target is either your device’s screen or the files that are on it. It is believed that Ransomware originates from Russia and that it has been developed sometime during the nineties. What you should be aware of regarding Ransomware is that no matter what it locks-up, such a virus asks for a ransom later in exchange for the decryption of the affected component of your device. 

.Crab Virus Ransomware

There are several different Ransomware subtypes and we are going to be talking about them below:

  • There are certain Ransomware programs that could block your tablets’ and mobile devices’ screens. What happens is that a large ransom-demanding pop-up gets displayed and blocks your access to the affected screen. Thus, you cannot reach any icons and shortcuts there or perform any operations. In this way the hackers want to force you to pay the requested ransom to make your screen available again.
  • Some Ransomware versions could affect your PC and laptop desktops. The manner of action really resembles the way such malware attacks mobile devices – by broadcasting a really big ransom alert and making you pay for its removal. Again, you are rendered unable to access anything on your desktop and you are supposed to pay for reversing that.

The most common and dangerous Ransomware category is the file-encrypting one:

Even though there are two other Ransomware subgroups, the data-encryption causing viruses represent the biggest and the most dangerous third subcategory. What its representatives could perform on your PC is the following:

  • After successfully invading your system, such viruses may target some particular file formats and strive to encrypt them all. The encryption process represents the following activity – the original file is duplicated and then deleted, leaving only the copy. The said copy, though being identical to the original, is protected by a complex encryption making it inaccessible unless the user has a special key for decrypting the file. That’s what you are later asked to pay for – for the decryption password/code. The blackmailing is done via a ransom note which gives you all the details about the ransom payment, amount and also potential threats about the future of the encoded data if the money doesn’t get paid. Such an extensive encryption process might take a while as well as a lot of system resources, which makes it sometimes visible. In case something slows down your PC, check your Task Manager as a virus like .Crab Virus Ransomware might have infected your machine.
