What is Trick Or Treat ransomware virus?

Trick or Treat ransomware is still in development stage

Trick or Treat ransomware

Trick or Treat is a crypto-malware, designed to remove access to your computer by locking the screen. There is still not enough information whether the ransomware is capable of encrypting your data. However, as soon as it is installed, it drops a vssadmin.exe file to delete shadow volume copies from Windows OS and makes sure that the user will not be able to recover his or her data.

Later, a window displaying the ransom note appears, and criminals provide further details to their victims on how to get access to their computers.

The amount of the ransom demanded is still unknown, but you shouldn’t motivate criminals by agreeing to follow their rules. Typically, victims have no guarantees that they won’t be asked for even more money after the transaction. Instead, you should rely on a professional anti-malware system and immediately remove Trick or Treat virus.

Even though there is no proof to claim that the ransomware encrypts your data, the screen lock function doesn’t allow you to access your computer. Experts say that it might modify Windows registry settings in order to launch the malicious program every time you turn on your computer. Thus, inexperienced computer users might face some issues, if they try to start a Trick or Treat removal.

Our IT specialists recommend opting for an automatic elimination of the ransomware. You can employ FortectIntego or any other reliable security software. It will detect the corrupted files and quickly get rid of the virus. Shortly after, you will be able to try to recover your files using backup copies[1] stored in the cloud.

According to the analysts, there are no official records of what extensions this crypto-malware appends to the encoded files. But be aware that the malware might still be in development stages and evolve to be able to encrypt your data using sophisticated algorithms. Thus, do not try to delete or uninstall executable files that you consider related to the virus. Terminating processes or eliminating essential files of the operating system might do severe damage to your computer.

Trick or Treat virusTrick or Treat virus is one of the first Halloween-themed ransomware viruses of 2017.

Malware spreads via spam email attachments or infected links on social networking platforms

According to,[2] cybercriminals employ more than one way to distribute this high-risk computer infection. It has been recorded, that malware infiltrates on the computer once the victim opens an attachment holding an executable file of the ransomware. It immediately infects the computer and blocks the victim from accessing it.

Besides, cybersecurity experts claim that the malicious program was noticed spreading via social media or other websites used for sharing files (e.g., DropBox). Thus, we strongly recommend you to avoid visiting suspicious sites or downloading software from unauthorized developers. If you still attempt to install an unknown program, scan it for malware beforehand.

Moreover, you should ignore vague messages[3] sent by your friends or people you don’t know. Crooks often hack into accounts to use them as a tool for spreading links that might redirect you to websites distributing high-risk computer infections.

Get back the access to your computer by eliminating Trick or Treat virus

You can start your Trick or Treat removal process by downloading a reliable anti-malware system. Choose wisely since some of the programs offered on the web are used to swindle money from naive computer users and are useless in case of a severe computer infection.

Once you install the security software, let it run a full system scan and get rid of the virus. It is a wise decision to eliminate it automatically since the software will also protect your computer and data from attacks like this in the future.

Bonus: Recover your data

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

You can restore files using data backup, however, since the majority of computer users fail to create them in time, we have provided a couple of alternative data recovery options. Keep in mind that they might not work as the ransomware corrupts your files strongly.

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

Test Data Recovery Pro

You can try Data Recovery Pro to restore some of your files. The tool was designed to recover corrupted or deleted files, but it might help you to recover files corrupted by Trick-or-Treat virus as well.

  • 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 Trick Or Treat ransomware;
  • Restore them.

Shadow-Explore your computer

There is another handy tool called ShadowExplorer. We suggest using it for recovery of the encrypted data. However, if the virus managed to delete Volume Shadow Copies, this software might appear useless in such situation.

  • 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.

Try tools suggested by the No More Ransom project

There is an useful website dedicated to helping ransomware victims recover their files for free. We suggest you to try their tools to recover your files. Visit NoMoreRansom site and see what tools they have to offer.

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

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
