Tyrant Ransomware - How to remove

Tyrant Ransomware is a dangerous virus that in case of infection will ask you for $15 ransom in exchange of your personal files, which will be encrypted. Even though fifteen USD is not that much, you should not pay the ransom and instead of that look for other ways to solve this problem. In fact, we are here to help you solve this situation thus continue reading the article and lear how you can kill Tyrant Ransomware infection.

Tyrant virus specifics

This infection is a typical ransomware infection because once installed on your computer it will try to encrypt files stored on your hard drive and then ask for the ransom in order to retrieve them.

As defined by Wikipedia article about ransomware, ransomware is “a type of malicious software from cryptovirology that threatens to publish the victim’s data or perpetually block access to it unless a ransom is paid. While some simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion, in which it encrypts the victim’s files, making them inaccessible, and demands a ransom payment to decrypt them.”

In this case, Tyrant ransomware virus tries to make you pay for locked files and receive a special key that would unlock them. It is spreading via several different methods. Regardless if you receive the payload file via spam email or some social files sharing platform, it will automatically drop malicious files onto your computer and install the ransomware.

Once that is done, the infection will scan all files stored on your computer and add unique extension to every single one of them. It is not known yet what extension is added by Tyrant ransomware, but the fact is that you won”t be able to open your files after that.

Once the encryption process is over, you will notice that your screensaver is changed and there are a lot of unknown symbols (unless you are Persian. It is so-called ransom-note that will provide you with the information about current situation and instructions to pay the ransom. Original text of the ransom note translated to English:

Your files are encrypted. You have 24 hours to pay the ransom of $ 15 dollars. Payment will increase further depending on the time that has passed after the first 24 hours…
The file decryptor will be sent to you after receiving the demanded payment. If you have any questions, please contact us by email, we will answer you…
Praise be to Allah, and in the Afterlife!

As you can see, you have 24 hours to pay $15 to the hackers. It is a classic technique to scare users and force them to pay. It is obvious that the ransomware was developed by Persians or that it is targeted to the market of users speaking Persian, but that does not mean that it can’t infect users from other regions.

We highly suggest not to pay the ransom, because there are no guarantees that you will retrieve your files even if you do so. Your files can be restored from the backup, but first of all, you have to take care of this infection and eliminate it. The best way to do it is to download trustworthy anti-malware application, such as Spyhunter. Scan your system with either one of them and the virus will be gone instantly.

Now, you can try to restore your files. We suggest you to take a look at our system restore guide. In case you still have some questions regarding this topic, feel free to ask them in the comments section below.

How to recover Tyrant Ransomware encrypted files and remove the virus

Step 2. Complete removal of Tyrant Ransomware

After restoring your system, it is recommended to scan your computer with an anti-malware program, like Spyhunter and remove all malicious files related to Tyrant Ransomware. You can check other tools here.  

Step 3. Restore Tyrant 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 Tyrant 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 Tyrant 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 a data recovery program.
• 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.
