Tk ransomware demands 1 BTC in exchange for the decryption key

The ransom note by Tk ransomware

Tk virus functions as a ransomware-type infection which uses AES algorithm[1] to encrypt the most valuable data. It was first discovered at the beginning of January 2017 demanding to pay 1 Bitcoin for the decryption tool. The original filename of this file-encrypting virus is your files have been encrypted.exe. 

Users report receiving the following message after Tk attack:

your files have been encrypted 
send 1 BTC to 1F1tAaz5x1HUXrCNLbtMDqcw6o5GN7xX7 

Usually, criminals indicate a specific e-mail address for contact purposes. However, Tk ransomware directly provides the Bitcoin account to which people should make the transaction to recover encrypted files. Although, obeying the rules of the crooks is not the best decision.

There are numerous cases when people agreed to pay the ransom and were tricked by the empty promises of the cybercriminals. Therefore, we suggest you to remove Tk virus instead of paying the demanded money. You can always recover encoded information from the backup copies stored in the cloud.

If you do not have them, feel free to use alternative data restore techniques which are presented at the end of this article. However, do not forget that you will only be able to proceed to retrieving your data after Tk removal. You can do that with the help of Reimage Reimage Cleaner Intego or SpyHunter 5Combo Cleaner depending on your preference. 

Please, do not try to eliminate TK ransomware virus from the system on your own. These attempts might end up with the irreparable damage to the system. File-encrypting viruses can affect legitimate system processes or hide under the safe-looking names, so you might be tricked and uninstall wrong entries.

Watch out suspicious spam emails and questionable software installers to avoid ransomware

Ransomware mostly spreads via malicious spam emails. These letters are perfectly crafted using social engineering strategies. Therefore, users can be easily tricked into opening a safe-looking attachment.[2]

Usually, these emails inform about a serious issue or ask to check the information provided in the attached Word, Excel, or another legitimate-looking website. However, once opened, malware executable is dropped on the system.

However, other malware distribution might be used to spread TK ransomware as well. For instance, criminals might use fake software downloads or updates that might be delivered in the form of pop-up or available on the questionable file-sharing websites, torrents or P2P networks.

Security specialists from[3] also suggest being careful with eye-catching ads, installing software and OS updates, and secure remote desktop connections. Additionally, creating backups should be on your priority's list as well. You can never know what tricks developers of ransomware might create for you.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Tk from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by Tk, you can use several methods to restore them:

Experts recommend Data Recovery Pro

We strongly suggest you try recovering files with this professional tool. Additionally, it can help you to restore files if you have accidentally deleted them.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Tk ransomware;
  • Restore them.

Windows Previous Versions feature can be handy

You must first check if System Restore was enabled before Tk virus infiltration to use this application. If it was, follow the guidelines below.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer can be useful

Fortunately, Tk ransomware currently does not delete Shadow Volume Copies from the victimized computers. Likewise, you are free to use this alternative recovery software.

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Sadly, but there is no official Tk decryptor yet

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Tk and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
