How to remove Stopdata virus and restore encrypted files

If you've encountered a ransomware and you're sure that it’s the Stopdata ransomware – here you will find useful information. We propose simple and tested instructions for Stopdata removal and possible manners to get back the corrupted information.

What is Stopdata



Let's find out, what do we know about ransomware? It is founded on a completely legal encryption system which modifies all data on operator’s machine and makes them unreadable if you have no key. That key is also encrypted with a different method. As usual, these algorithms are AES and RSA, that have asserted themselves the very hard-to decrypt and fail-safe. The mentioned algorithms and the programs built upon them are in public access in the Net, so web-criminals only need to invent security techniques, to restrict an admittance to a virus, and make the flawless control and update pattern. Some pieces of ransomware just function independently, and web-criminals know about a new "client" not before he approaches them and sends the ransom. Other encrypting viruses are highly active, and transmit data to thousands addresses, to puzzle the malware-fighters and maximize the efforts required to beat a ransomware.


“All your important files were encrypted on this PC.

All files with .STOPDATA extension are encrypted.

Encryption was produced using unique private key RSA-1024 generated for this computer.

To decrypt your files, you need to obtain private key + decrypt software.

Ransomware kind is not significant, as the AES and RSA algorithms are too tricky difficult to bruteforce them. It it requires hundreds of years to carry out all necessary operations on a common computer or, possibly, twenty or thirty years if you can use a super-powerful gear. There are two efficient manners to beat an encrypting virus: to hack into it, or break into the Command & Control website, to receive encryption keys. In some cases there is a switch that can cease virus' activity in full or to leave unscathed the infected PC. If anyone finds that switch for this ransomware, or develop a decryption program, we will update this guide.


There are a few possibilities to examine, prior to yielding and looking for a decryption software. As we said earlier, swindlers make mistakes, and certain peculiarities of your Windows might support you to recover information.


  • If you've made a backup, kept on an external drive – just delete a ransomware and use it. Ensure that Stopdata is uninstalled fully, as if it isn't – all data will be corrupted again, including those that were kept on an outer hard disc.
  • If you don't use the system via an admin account – it's your happy day. The catch is that the OS makes backups of all data before their removal or alteration. Suchlike backups are known as the Shadow Volume Copies, and the virus has the manners to destroy them. If you're using the user's account – the operating system asks for a authorization at the very moment Stopdata tries to delete SVC. In case you've seen such confirmation and reversed it – your copies are secure, and might be used to recover the files.


If both of written above hints didn't work and there is no possibility to recover the files – you should delete Stopdata from your device and wait until a decryptor will be published.

How to remove Stopdata

As about the uninstalling – there’s no possibility to completely elude an installation of an antiviral. Stopdata is incredibly sly and you could miss some remains and then suffer from it (for example, when you attach an external drive with your saved files to a not-totally-cleared system). It also hides very well, so you just won’t be able to get rid of it fully with your own hands. Knowing this, we have created an efficient removal instruction which can assist you to beat this problem. It has a few manual steps and one optional anti-viral tool phase.
