1. Do not rename encrypted files.

2. Do not try to decrypt your data using third party software. It may cause permanent data loss.

The point is that all encrypting programs take advantage of the famous encoding algorithms, such as the AES and the RSA. They are simply the very complex ones, and you can't decrypt them. Of course, you may decipher them if you have a hundred years of common PC’s operation time or a few years of operation on the very efficient computing device of the world. We don't think that any of these variants suits you. It's time to learn that encrypting viruses are easy to avoid, but if it’s already in the system – it's a serious issue.

The encrypting programs, AKA ransomware, are the programs that penetrate users’ devices and waste their files to ask a ransom from them. The penetration is commonly carried out with the help of email fraud or zero-day Trojans. Hazardous message is pretty easy to define – you'll get it from an unknown sender, and it will have a file attached to it. If we talk about zero-day vulnerabilities, it’s way harder – you'll never feel that it's coming until the machine gets encrypted which means that the most effective defensive manner is to daily check for the updates the system and other utilities that you use.

The code of ransomware isn't really complex, yet even the most carelessly designed one is very hazardous, and we will prove our point. The catch is about the methods of encryption. Malicious programs don’t literally smug your data. It simply wants to penetrate the machine, spoil the files and remove the originals, leaving the spoiled files in their place. The files are unreadable when they are encrypted. You cannot read them and can’t return them to their previous state. There are not many manners to recover the information, and they all are explained in this piece.

If the ciphering is performed, hackers give you a ransom message, and when it popped up – you can be sure that the information is spoiled. There's only one measure you can take now - to delete ransomware from the hard drive and attempt to recover the data. We've said “try” because the chances to achieve success without a decryption program are ghostly.

How to remove GreyStars

It’s crucial to eliminate ransomware before you proceed because if it remains on your computer – it will begin encrypting any file that enters the computer. You should understand that any device you're linking to the infected machine will get ciphered also. To evade that – eliminate ransomware by following this effective removal instruction. Remember that the uninstallation won’t reverse the virus' doings, and if you do this, you will not be able to pay the ransom. It will be smart that since every ransom gained makes hackers more confident in what they do and gives them more budget to develop other viruses. The important thing is that if you’re forced to deal with scammers, they won't give you a assurance that the data will be decrypted after you give out the money. They have just ciphered your data, and you, probably, don't want to give them your money after that.

GreyStars decryption instruction

When the ransomware is removed from the PC, and you're sure about it, you should learn more about the restoration techniques. Primarily, we should say that the most proven way is to load the previously saved copies. If you had the copies of your information and the virus is completely removed – don't hesitate. Erase the encrypted data and load the copies. If there were no previously saved copies – the odds of restoring your files are much lower. The only way to make it is the Shadow Volume Copies. It’s the inbuilt service of the Windows OS, and it duplicates all the modified or deleted files. They may be reached with the help of custom recovery tools.

Naturally, the complex ransomware might remove these files, but if you use an entry without master rights, the virus just couldn’t do that without your permit. You may recollect that sometime prior to the showing of a scammer's letter there was another menu, asking to apply changes to the system. If you've cancelled those alterations – the copies are at your service, and you might access them and repair your files through the tools as ShadowExplorer or Recuva. You can easily find them both on the Internet. Both of them have their main websites, so you better download them there, with tested guides.
