CryptoShield Ransomware Removal Guide

Ransomware is one of the most dangerous malware types out there. Therefore, it is paramount that you protect your PC because ransomware is designed to encrypt your files and demand money for the decryption tool. CryptoShield Ransomware is a recently discovered ransomware-type program that does just that. It can enter your computer secretly and encrypt all of your files. Then, it will demand that you purchase the decryption key and software to get your files back. At present, no free decryption software can decrypt your files. Therefore, you should remove it instead of complying with the cyber criminals’ demands.

Your computer can become infected with CryptoShield Ransomware as a result of opening a malicious email attachment, visiting an infected website, or installing pirated software. We think that distribution via email is most likely as it has a high infection rate. We think that CryptoShield Ransomware’s main executable named SmartScreen.exe can be included in a file archive or a fictitious PDF or MS Word file that will download it to its destination folder. If it is distributed via infected websites, then it must rely on JavaScript and Flash vulnerabilities to get your PC infected. Of course, pirated software has always been a means to distribute malware, but it is rarely used today. Still, we do not rule out the possibility of this ransomware being distributed in this particular fashion. Now let us go into the details regarding the functionality of this ransomware.

The SmartScreen.exe executable is set to be dropped in %ALLUSERSPROFILE%\MicroSoftWare\SmartScreen. After that, it is launched automatically, and it starts encrypting your files immediately. According to our research, CryptoShield Ransomware uses the RSA-2048 encryption key. This ransomware generates a unique public encryption key that is stored locally and a private decryption key that is uploaded to a remote command and control server. To decrypt your files, you need to get the decryption key and, unfortunately, the only way to get it is to pay the ransom. We want to point out that this ransomware does not specify the amount to be paid for the decryption key. Once the encryption is complete, it will ask you to contact the developers using one of the three (restoring_sup@india.com, restoring_sup@computer4u.com, restoring_reserve@india.com) email addresses. Then you will receive further instructions on how to pay the ransom.

The cyber criminals use scare tactics to compel you to pay the reason. They state that if you do not pay the ransom within 72 hours of the infection, then this ransomware will delete all the encrypted files. However, you should refrain from paying the ransom because there is no way of knowing whether the cyber criminals will give you the decryption key.

In closing, CryptoShield Ransomware is a highly malicious application that can encrypt all of your files if it were to infect your PC. Therefore, you should remove it from your computer as soon as possible because it will then delete all of the encrypted files. You can wait for a free decryption tool to appear but there are no guarantees that it will. You can use SpyHunter, an antimalware application or the guide featured below to eradicate CryptoShield Ransomware.
