Nacro Virus Removal (+.Nacro File Recovery)

In the event that your computer has been secretly compromised by a Ransomware cryptovirus called Nacro, you may be at risk of losing some of your most important files. Ransomware infections like this one specialize in the secret encryption of many types of digital information, which people store on their machines. The files that Nacro targets may include images, documents, audio and video files, system files, and more, and the reason why such viruses are called Ransomware is because they demand a ransom payment in exchange for undoing the applied encryption. This ransom amount can range from anything several hundred to several thousands of dollars, depending on the virus, and the victims that have been targeted.

In case you have been infected, we think it’s important that you learn more about this virus before we provide you with the instructions on how to remove it. Therefore, we recommend that you read the information that follows, and after that make use of our detailed removal guide below.

How does the .Nacro virus work?

Ransomware cryptoviruses, such as Nacro, are some of the most terrible computer threats because they actually block the access to your personal files by means of file-encryption and then blackmail you to pay a ransom for their decryption. This is a sophisticated blackmailing scheme that is not only incredibly difficult to deal with, but also very tricky to prevent. The reason is, the Ransomware that does all that bad stuff to your data is typically very difficult to detect and manages to remain under the radar of most antivirus programs. That is because the file-encryption itself is not something harmful that corrupts the system or destroys your information. This is a data-protection method which is commonly used in many sectors where digital information should be kept safe from unauthorized access. Therefore, due to a lack of any actual damage, most security software does not identify the file-encrypting process as a threat.

People behind threats like Nacro, Coharos or Nasoh however, use that otherwise useful data-protection method as the basis for a money extortion scheme. They keep the decryption key, needed for accessing your files on their servers and ask you to pay a certain amount of money for it in order to obtain it.

Saving the encrypted .Nacro files

The hackers threaten that if you don’t pay the ransom, they will destroy the decryption key, and leave your important files inaccessible forever. Security experts, however, warn that giving your money to the hackers only encourages them to blackmail you even more. Besides, there is no guarantee that after you fulfill all of their demands they will really send you the decryption key, let alone that it will work.

Therefore, our suggestion is to focus on removing the insidious Nacro from your computer and then try some other ways of restoring your sealed files. The removal guide below will help you with that. There is also a section with some file-recovery suggestions, which don’t involve paying ransom to anyone. Feel free to give them a try, and let us know if you have any questions by leaving us a comment below the article.
