7h9r Ransomware - How To Remove?
7h9r ransomware uses sophisticated asymmetric (RSA and AES) encryption algorithm to encrypt the files of the targeted victim. It is regarded to be a derivative of the both Nemucod ransomware and Xorist ransomware by some security experts. On the whole, there is a mutual agreement between experts and users who have suffered a ransomware attack that the worst thing can happen to one’s computer is the ransomware virus infection.
About 7h9r Ransomware
This ransomware (like many other) bears its name form the filename extension it ads to the filename extensions of the encrypted files, which is .7h9r. For example, image.bmp is rendered into image.bmp.7h9r. This cryptomalware easily encrypts more than 70 file types. Though it does not replace your desktop wallpaper like other ransomware threats, 7h9r cryptomalware does drop README_.txt file on your desktop and in all folders of encrypted files. This text file embodies the ransom note which contains email@example.com e-mail address to be used to contact the cyber crooks. The size of the ransom demanded is 100 USD at the moment, which is to be paid in bitcoins.

There is no decryptor available at the moment but as soon as it will be released, we will update this article and provide you with the clear step-by-step decryption procedure. Even though there is no 100 per cent decryption option at the present moment, do not fall for the hackers scheme. You will only lose your money. And, what is more, 7h9r ransomware may install a backdoor trojan to gather your bank card data. For the time being, you can make an attempt to apply data recovery tools such as R-Studio, PhotoRec or tools by Kaspersky Lab. Cloud, One Drive, Google Disk file hosting services are great preventative measures to be taken in the future if you have not secured your data by such means before. The usage of removable drives is also highly recommended.
Spyhunter, Reimage or Malwarebytes, one of these security utilities, are to be applied before performing any file recovery procedures. Crypto ransomwares usually re-encrypt the data if they do not delete themselves after the encryption or if they are not eliminated. Ransomware viruses also tend to install other threats along with them, so a powerful malware removal tool is essential for your computer’s system. There is an option of manual removal as well.

Step 3. Restore 7h9r Ransomware affected files using Shadow Volume Copies
If you do not use System Restore option on your operating system, there is a chance to use shadow copy snapshots. They store copies of your files that point of time when the system restore snapshot was created. Usually 7h9r Ransomware tries to delete all possible Shadow Volume Copies, so this methods may not work on all computers. However, it may fail to do so.
Shadow Volume Copies are only available with Windows XP Service Pack 2, Windows Vista, Windows 7, and Windows 8. There are two ways to retrieve your files via Shadow Volume Copy. You can do it using native Windows Previous Versions or via Shadow Explorer.a) Native Windows Previous Versions
Right-click on an encrypted file and select Properties → Previous versions tab. Now you will see all available copies of that particular file and the time when it was stored in a Shadow Volume Copy. Choose the version of the file you want to retrieve and click Copy if you want to save it to some directory of your own, or Restore if you want to replace existing, encrypted file. If you want to see the content of file first, just click Open.
b) Shadow Explorer
It is a program that can be found online for free. You can download either a full or a portable version of Shadow Explorer. Open the program. On the left top corner select the drive where the file you are looking for is a stored. You will see all folders on that drive. To retrieve a whole folder, right-click on it and select “Export”. Then choose where you want it to be stored.
Step 4. Use Data Recovery programs to recover 7h9r Ransomware encrypted files
There are several data recovery programs that might recover encrypted files as well. This does not work in all cases but you can try this:
- We suggest using another PC and connect the infected hard drive as slave. It is still possible to do this on infected PC though.
- Download Data Recovery Pro (commercial)
- Install and scan for recently deleted files.
Note: In many cases it is impossible to restore data files affected by modern ransomware. Thus I recommend using decent cloud backup software as precaution. We recommend checking out Carbonite, BackBlaze, CrashPlan or Mozy Home.
Important Note: Although it is possible to manually remove 7h9r Ransomware, such activity can permanently damage your system if any mistakes are made in the process, as advanced spyware parasites are able to automatically repair themselves if not completely removed. Thus, manual spyware removal is recommended for experienced users only, such as IT specialists or highly qualified system administrators. For other users, we recommend using Reimage or other tools found on 2-viruses.com.
