A 1.1 version of the CryptoShield 1.0 ransomware has been detected using the same .cryptoshield appendix on the files it encrypts. The ransomware virus was first detected using the same extension, but the newly modified version also includes improvements in the encryption algorithm as well as other fixes. What is the most significant change is that this ransomware virus uses the latest RIG-V exploit kit to cause infections undetected. Keep reading this article to learn how to remove this virus from your computer and attempt to restore your files in case they have been encrypted by it.
More Info on CryptoShield 1.1 Virus
The purpose of this ransomware virus is to use encryption to render the files on the computer no longer able to be opened by the user. The virus also performs other malicious activities on the computer, like touching some files in the Windows Registry Editor as well as starting processes in the Windows Task Manager to encrypt data. Le CryptoShield 1.1 ransomware may also execute privileged commands, such as the VSSADMIN command that deletes the shadow copy backups on the compromised computer.
But this is not everything. Le CryptoShield 1.1 ransomware also is very active when it comes to encrypting files. To perform the encryption, the virus uses ROT-13 mode to encrypt files in AES-256 cipher. Puis, the virus adds it’s distinctive .cryptoshield file extension, for example Word File.doc.CRYPTOSHIELD.
But then, the ransomware virus also adds a # RESTORING FILES #.txt and # RESTORING FILES #.html files which are it’s actual ransom note.

Automatic Removal of CryptoShield
Recover files encrypted by the CryptoShield Ransomware.
Method 1: Using Shadow Explorer. In case you have enabled File history on your Windows Machine one thing you can do is to use Shadow Explorer to get your files back. Unfortunately some ransomware viruses may delete those shadow volume copies with an administrative command to prevent you from doing just that.
Method 2: If you try to decrypt your files using third-party decryption tools. There are many antivirus providers who have decrypted multiple ransomware viruses the last couple of years and posted decryptors for them. Chances are if your ransomware virus uses the same encryption code used by a decryptable virus, you may get the files back. Cependant, this is also not a guarantee, so you might want to try this method with copies of the original encrypted files, because if a third-party program tampers with their encrypted structure, they may be damaged permanently. Here are the vendors to look for:
Method 3: Using Data Recovery tools. This method is suggested by multiple experts in the field. It can be used to scan your hard drive’s sectors and hence scramble the encrypted files anew as if they were deleted. Most ransomware viruses usually delete a file and create an encrypted copy to prevent such programs for restoring the files, but not all are this sophisticated. So you may have a chance of restoring some of your files with this method. Here are several data recovery programs which you can try and restore at least some of your files:
