How to remove NazCrypt virus and restore encrypted files

If you have encountered an encrypting infection and have reasons to suppose that it is the NazCrypt ransomware – in our guide you'll find help. We offer plain and tested instructions on NazCrypt deletion and possible ways to restore the spoiled files.

What is NazCrypt

Encryption virus is a worricow of our society, and every user knows that if you can not open your files and you see a ransom note – it’s time to worry. It is a true, unfortunately. An encrypting virus is the worst threat that you may face on the Internet because a common customer literally can't delete it. The only situation when you can overcome ransomware is if you are not facing a real virus, but a fake, that covers the display and tries to trick you into paying a ransom. In all other cases, if ransomware was created and tuned in a right manner – you can only trust that specialists will beat it. If swindlers made a mistake, and there are some vulnerabilities, which allow you to recover data – you'll find an answer in the following guide.

 

 

Let's find out, what is NazCrypt? It consists of a totally legal cryptography system which ciphers all folders on user’s workstation and makes them useless without a key. Of course, a key is also encrypted with another method. As usual, scammers choose RSA and AES methods, which have proven themselves the most complex and reliable. The mentioned algorithms and the software built upon them are in free access on the Internet, so swindlers only have to develop mechanisms of protection, to block an admittance to a ransomware, and create the perfect update and control scheme. Some viruses might function on their own, and swindlers know of another "client" not before he approaches them and forwards the money. Other viruses are function in another way, and send data to hundreds URL's, to confuse the researchers and maximize the time needed to beat a virus.

 

NazCrypt adds next text to user's computers:

Ransomware sort is not significant, as the RSA and AES algorithms are very complex to bruteforce them. It will take hundreds of years to make all needed calculations on a standard device or, possibly, 2-3 decades if you will use an industrial gear. The best manner to beat a decent virus is to find flaws in its code, or hack the Command & Control website, to get encryption keys. Rare viruses also have a breaker, allowing to cease ransomware's activity in full or to drive it off a particular PC. If someone discovers such switch for NazCrypt, or publish a decryptor, we'll update this guide.

 

There are a few things to check, prior to giving up and expecting for a decryptor. As we said before, web-criminals make errors, and some specialties of your system may support you to recover data.

 

  • A backup is the sole completely productive way to recover your information, but you should delete a ransomware first. Ensure that the ransomware is eliminated in full, since if it’s not – all information will be encrypted again, including those that are on a flash disc.
  • If you employ an profile with no administrator rights – today’s your happy day. The point is that your OS duplicates all files until they’re destroyed or altered. These copies are called SVC, and the virus knows how to destroy them. If you are using the user's account – the system asks for a confirmation at the very second NazCrypt tries to delete shadow copies. In case you saw suchlike confirmation and reversed it – your SVC are alright, and might be used to recover the data.

 

If you checked all these opportunities and there is no way to recover the files – you better remove the virus from your computer and wait until a decryption software will be published.

How to remove NazCrypt

Unfortunately, you can't totally elude an automatic mode. NazCrypt is very tricky and you will definitely miss some elements and then suffer from it (it might happen if you line up an external drive with your saved information to a not-totally-purged computer). It also hides damn good, so you just can't uninstall it entirely in manual mode. Here's your elimination specification that will suit all your needs. It consists of a few by-hand steps and one optional anti-viral software step.

If you use a usual profile – you have feeble chances for file recovery, but you will need peculiar recovery tool. The most effective ones of them are Recuva or ShadowExplorer programs. You can download these programs simply on the registered pages of their owners, with close guides.
