How to remove Mosk virus and restore encrypted files

If you've faced a ransomware and have reasons to suggest that it’s the Mosk program – in our item you'll find useful information. We offer plain and tested instructions for Mosk deletion and potential methods to restore the wasted data.

 

Encryption virus is a scarecrow of mankind, and everyone knows that if you can't access the files and there's a ransom note – it’s time to worry. It’s a valid reaction, by the way. Ransomware threat is the ugliest thing that might happen to you on the Internet since a common person has no resources to eliminate it. The single event when you're able to beat ransomware is if you are not facing a true virus, but a fake, that covers your screen and attempts to lure your funds. In all other cases, if a virus was created and secured in a right method – you can only expect that virus fighters can defeat it. If fraudsters failed somehow, and a virus has some drawbacks, which allow you to recover data – you'll find an answer in this article.

 

 

Ransomware type is not important, as the AES and RSA algorithms are very complicated to decipher them directly. It will take centuries to execute all required operations on a modern machine and, maybe, twenty or thirty years if you will use a super-efficient gear. The best manner to neutralize a decent encrypting malware is to hack into it, or hack its database, to find encryption keys. Rare ransomware examples also have a breaker that can cease virus' activity in full or to make it pass the infected machine. If some parson finds such switch for this ransomware, or publish a decryptor, we will update this article.

 

So, what is ransomware? It is founded on a completely legal coding algorithm that modifies all folders on user’s workstation and makes them unreadable without a key. Of course, a key is also encoded with a different manner. As usual, scammers choose RSA and AES algorithms, which are famous for their complexity and fail-safety. These methods and the programs built upon them can be easily found in the Net, so web-criminals just need to add protective mechanisms, to block an access to a program, and make the perfect control and update system. Some viruses just function on their own, and scammers get a report of a new "client" only when he writes them and sends the money. Other encrypting viruses are function in different manner, and send data to hundreds servers, to puzzle the researchers and maximize the work required to defeat a ransomware.

 

There are some alternatives to inspect, before you can yield and wait for a decryption software. As we said earlier, Internet-criminals also fail, and some characteristics of the system may serve you to recover information.

 

  • A backup is the sole totally effective way to get your information back, but you should remove a ransomware first. Ensure that Mosk is deleted entirely, since if it’s not – all data will be corrupted again, with the files that were stored on an outer hard drive.
  • If you utilize an entry with no admin authorization – it's your happy day. The matter is that your OS creates copies of all information until their deletion or modification. Suchlike backups are called Shadow Volume Copies, and Mosk knows how to destroy them. If you are operating from the regular account – the system requests for a confirmation at the very moment Mosk starts to remove SVC. In case you saw suchlike confirmation and declined it – your copies are safe, and might be used to recover the data.

 

If both of these hints didn't help and you have no way to restore your data – you should eliminate Mosk from your PC and wait until a decryption software will be published.

How to remove Mosk

As for the deletion – there’s no possibility to completely avoid an installation of software. Mosk is too tricky and you could pass some remains and then regret it (for example, when you connect a flash drive with your saved data to a not-completely-purged system). It also conceals damn good, and you just won’t be able to get rid of it entirely with your own hands. Knowing this, we have made a decent removal specification which will suit all your needs. It has some manual phases and one extra anti-viral tool step.
