What is .MCNB File Virus

.MCNB Ransomware is a data locker malware that encrypts all digital files on a compromised PC. It only converts files into inaccessible format then demands extortion money to restore files. This dubious threat is blackmailing malware that prevents users from accessing their personal files and forces them to pay money to reverse the encryption. It is able to attack all versions of Windows computers without the permission of the user. Upon successful intrusion, the .MCNB virus will scan the entire computer for files. Then it encrypts all the files on that PC which normally include but not limited to video, audio, images, text documents, backup, archives, and so on.

Once done with the encryption method, .MCNB File Virus will leave a ransom note on the infected PC to inform victims about the attack. That note will contain all the information about this dubious malware and the ransom demand. The message on that note clearly states that the only way to recover encrypted files is by purchasing the decryption key. Although this .MCNB Ransomware claims to restore your files after paying the money, it is only a trick. Hackers are only intended in making illegal profits by cheating innocent victims.

What happened to your files

The ransomware infection has become a new reality these days. This dirty little malware can easily target your system and you won’t even know it. It will too late when you will ever realize that your computer is infected and you cannot access your files anymore.

Once infecting your computer, .MCNB Virus will change all your files and you will lose access to your private information. It adds its own extension to mark files as locked, and you will need the decryption key to unlock such files and that you can only get from hackers for a price. This is illegal and sure very painful for the victim’s but cybercriminals are making good money out of it.

NEVER Pay Ransom Money

As I have already mentioned, do not pay ransom money to hackers. They are not intended to restore your files. No matter how tempted you are, first, you need to think it through. You don’t know hackers, payment is in BitCoin which cannot be traced, and after getting the money they don’t have any reason to decrypt your files. The only leverage they have on you is your files.
