That article is about virus called NHCR which infects users' PC in all countries of the world, and corrupts the data. Here you can find important information on NHCR's essence, and how to get rid of NHCR from the laptop. In addition, we'll tell you how to restore the cyphered files, if possible.

NHCR ransomware virus

NHCR is the unwanted program penetrating PC's mostly with help of Trojans and phishing e-mails. Occasionally scammers use exploits to take control over the system, but big program developers quickly fix them. When infection is done, the virus checks the PC memory, defines the quantity of files to be encrypted and their approximate value. Currently, each modern virus can cypher text, image, video and audio information in all popular formats. High attention is paid to businesslike files, since representatives of business are the main target for hackers. NHCR encrypts only information, and doesn't touch the programs, so that the man can pay the ransom through his computer. Encryption is performed with the help of world-known encryption algorithms, and its intricacy is so high that it cannot be bruteforced. This is the root for impressive efficiency of ransomware in recent years: common user, even if he has a fairly high knowledge of the computer, will never recover the data, and will have no choice except paying to criminals. The sole manner to recover files is to hack the fraudster's site and get the encryption keys.

For any kinds of malicious programs, one statement is correct: it is much easier to prevent it than to cure it. Statistically, most people see the significance of computer literacy just after ransomware infection. You easily can decrease the chances of getting ransomware by following these advices:

  • Be careful with the e-mails which contain data. If you don't know the person who send an e-mail and it notifies about winning any prize, a lost parcel or something similar, this could be a scam message. You also should keep an eye on business correspondence, especially if the sender's address and the content is unknown. It is normal to take an interest and open the letter even if it's sent to the wrong address, but remember that one click on the attached file may cost you lots of time, efforts and money.
  • Monitor the state of your computer. It requires a big part of computing resources to encrypt the information. In the first seconds of infection, the workstation slows down, and the encryption process can be found in Process Manager. You may recognize this event and unplug the PC before information will be totally lost. Of course, some files will be encrypted, but the rest of them will remain intact.
  • Do not accept any alterations to the system, originating from weird programs. If the computer is polluted by ransomware, it will endeavour to delete all copies of the files, to make the recovery less possible. However removal of shadow copies needs admin rights and acceptance from the operator. If you'll think for a moment before accepting the changes, it might save your information and your money.
