How to remove CryptoManiac virus and restore encrypted files

If you've faced a ransomware and you're certain that it’s the CryptoManiac ransomware – here you will find useful information. We suggest easy and effective advice about CryptoManiac elimination and possible ways to restore the wasted information.

What is CryptoManiac

Every PC operator knows that if you can't open your data and there's a ransom note – it’s time to worry. It is a right reaction, unfortunately. Ransomware infection is the worst threat that you can face on the Internet because a common person literally can't get rid of it. The single event when you're able to defeat ransomware is if you aren't dealing with a true one, but a dummy, that blocks the display and attempts to lure your money. In all other events, if a virus was created and secured in a right way – you should just trust that specialists will defeat it. If swindlers failed somehow, and a ransomware has some drawbacks, that allow you to recover data – you'll find a cure in this guide.



Let's find out, what is CryptoManiac? It is founded on an absolutely legitimate coding system which modifies the data on operator’s computer and makes them useless if you have no key. That key is encrypted too, but with a different method. As usual, these methods are AES and RSA, which are known for their complexity and reliability. The mentioned algorithms and the programs built upon them are in public access in the Net, so scammers only need to add mechanisms of protection, to block an inlet to a program, and make the safe control and update system. Some encrypting tools may act in standalone mode, and scammers get a report of a new "client" only when he turns to them and forwards his funds. The best encrypting viruses are work in another manner, and deliver files to thousands addresses, to puzzle the security specialists and throw them off virus’ track.

Regardless of ransomware’s type, the RSA and AES methods are overly tricky difficult to decipher them directly. It it requires thousands of years to execute all required calculations on a common machine and, possibly, 3-4 decades in case of usage of a super-powerful gear. We know only two effective manners to beat an encrypting malware: to hack it, or hack its server, to get a master key. Rare viruses also have a switch, able to cease ransomware's activity completely or to drive it off the infected PC. If anyone finds such switch for CryptoManiac, or make a decryption program, we will update this guide.


Here we've gathered several things to examine, before yielding and looking for a decryption tool. As we said earlier, scammers also fail, and certain specialties of your OS may support you to get back your information.


  • A protected copy is the only completely efficient way to recover the data, but you should uninstall CryptoManiac prior to it. Make sure that CryptoManiac is eliminated completely, as if it’s not – all data will be encrypted one more time, including those that were saved on a flash disc.
  • If you utilize an account with no admin rights – today’s your fortunate day. The thing is that your OS duplicates all data before their deletion or alteration. Suchlike files are known as the SVC, and CryptoManiac has the ways to destroy them. If you are employing the regular profile – the system asks for a authorization at the very moment CryptoManiac tries to remove SVC. If you saw such window and reversed it – it means that the SVC are alright, and might be used to restore the information.


If both of these advice didn't work and you have no way to get back corrupted files – you better uninstall the virus from the device and expect when a decryptor will be developed.

How to remove CryptoManiac

Unfortunately, there’s no chance to completely escape an automatic mode. This ransomware is too tricky and you can pass some elements and then suffer from it (it might happen if you attach a flash data storage with the saved data to a not-fully-purged computer). It also conceals pretty good, and you literally can't remove it completely in manual mode. Here's your uninstall guide that will suit all your needs. It has some by-hand steps and an extra AV tool stage.
