DecryptFox virus Removal Guide

What is DecryptFox ransomware?

DecryptFox ransomware – a file-locker which gives five attempts to enter the code for data recovery

DecryptFox ransomwareThe ransomware is a dangerous computer virus that uses the AES encryption algorithm to lock important documents on the infected PC.

DecryptFox ransomware is another file-encrypting virus that enters the system through dubious-looking email messages and starts its damaging activities by creating new registry entries[1]. Furthermore, it uses the AES cipher to encrypt files on the infected PC. Once that happens, all blocked documents appear with the .encr extension and remain useless.

After that, the ransomware displays a ransom message which is named readmy.txt and urges to contact the criminals via email address and send your ID[2]. However, such crooks are very likely not to fulfill their promises to give the necessary code after contact, so a better option would be to get rid of the infection.

Name DecryptFox
Category Ransomware
Extension .encr
Ransom message readmy.txt
criminal contact email
Encryption method AES related
Starts activity in Windows Registry
Spreading Spam messages and their attachments
Removal Eliminate the infection with our recommended time-proven anti-malware tools
System repair Use the FortectIntego system diagnostics tool to fix all system irregularities that could cause various abnormal PC behavior if left unattended

Crooks who spread DecryptFox ransomware, differently from others, do not urge any particular ransom but ask to send the ID to the given email address. However, be careful with such things. Revealing personal information will not bring anything good, furthermore, users are often left scammed by cybercrooks and do not receive any decryption tool.

Moreover, ransomware uses a unique encryption algorithm such as AES. The codes are different each time when the virus enters a new computer system. This and the difficulty of the code itself make it almost impossible to identify even for highly experienced users or technology experts.

Never mind the beforementioned fact, a better option would be to remove DecryptFox virus from your computer system permanently by using automatic tools and then think about file recovery. Such time-tested software as SpyHunter 5Combo Cleaner or Malwarebytes is capable of removing any cyber threats and protecting your devices from them in the future.

Once you get rid of the cyber threat, you can use FortectIntego to repair all damaged objects if there are some. Talking about locked files, you can look for decryption solutions below this article. Another important reason to perform the removal of the file-locking parasite is that some viruses have abilities to secretly create paths for other malware forms to spread.

This might lead you to stealth infiltration of another similar threat and even a Trojan horse. Note that removing the ransomware manually is not a possibility as the virus itself and all its components might be too hard to detect for a less-experienced user.

DecryptFox ransomware virusThe file-encrypting cyber threat can enter the system through a phishing email message.

Opening an infected spam email might result in a ransomware infection

According to tech specialists from[3], ransomware is usually spread through phishing messages. Some crooks decide to send hazardous content attached to the email to numerous random users. When that happens, users receive the dubious email in the spam section, however, sometimes it may also fall in the inbox.

If you ever overcome a suspicious-looking email letter with some attachments, be careful and do not enter such content as a virus might be hiding there. Furthermore, you can find virus-related content on a third-party promoted website. Some pages, especially P2P[4] ones, come improperly disclosed and might lack recommended protection.

This lets random criminals inject hazardous components into links. If a user steps on such a hyperlink, he/she might easily start the installation of ransomware and get his/her computer system infected. Stay away from questionable websites, if you ever encounter one, make sure you eliminate it immediately.

Bonus: Recover your data

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

If you have discovered some files on your desktop that have the .encr appendix, that means those documents are locked by ransomware. To restore important data back, you will need to go through some decryption methods that we have provided below. Make sure you choose the most suitable one for your case.

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

Data Recovery Pro might help you get important data back:

Try this tool to restore encrypted documents. Make sure you complete each step as required to reach the best results.

  • 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 DecryptFox ransomware;
  • Restore them.

Use Windows Previous Versions feature to unlock documents:

This method might be helpful and will let you restore encrypted files. However, it might not work properly if you didn't enable the System Restore function before the virus showed up in your system.

  • 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”.

Using Shadow Explorer might help get some files back:

You can try this tool to unlock some files that were blocked by the ransomware virus. Note that this method will work only if the Shadow Volume Copies remain untouched by the dangerous infection.

  • 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.

Cybersecurity experts haven't discovered an official decryptor for this ransomware yet.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from DecryptFox 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.
