Pidon ransomware. Djvu version emerges again

Pidon virus Removal Guide

What is Pidon ransomware?

Pidon ransomware is one version out of hundred that came out in Spring 2019 from Djvu ransomware creators

Pidon ransomware Pidon ransomware is another variant of the infamous Djvu (STOP ransomware).

Pidon ransomware is one of many versions in the Djvu family that uses, as contact emails. These emails get displayed as the primary way for contacting these criminals in a ransom note file delivered as _readme.txt that also states about possible test decryption and contains ransom demand that is $980 for the decryption key. Although criminals offer to lower the price by half if you write them in less than 72 hours, we recommend staying away from these people in general.

Especially when Pidon ransomware virus belongs to a notorious ransomware family dubbed Djvu ransomware that is possibly decryptable with STOP decrypter (direct download). There is no need to contact cyber criminals when you can remove the virus from the machine and wait for the needed update of this decryption software. However, remember to clean the system before recovering any of your files, so there is no risk of permanent damage.

Pidon ransomware is the cyber threat that focuses on the encryption process during which the original code of the photo, video, or a document or even database gets changed to make the data useless. This is the main process that cryptovirus as such start the attack with. However, a few things get done before this.

Any malware creators, especially cybercriminals behind crypto-extortion based malware like Pidon ransomware, try to keep the threat as persistent as possible, so there is more damage done on the affected device. This is achieved by:

  • changing startup preferences;
  • altering the existing ones or adding new registry keys;
  • disabling security features and programs;
  • installing other files or applications;
  • deleting Shadow Volume Copies or other data.

Once all the needed processes get run by the Pidon ransomware, and the system is checked for any other malware, the encryption process starts. This is file-encoding ransomware, so the virus is not going to waste time. The goal is to make peoples' personal files useless and demand the payment or even infect the machine with malware.

Pidon virusPidon virus - ransomware that might relate to the deletion of Shadow Copies.

Unfortunately, when ransomware gets on the system, it runs in the background silently, and the victim cannot know when or where from the virus came. However, all the processes are fairly quick, and when Pidon ransomware finds all the files for file-locking, it encodes them so the ransom can be required.

Once data gets encrypted, all the files get appendix .pidon to mark them. This process is also unnoticeable as other functions of the virus, but then Pidon ransomware delivers the ransom note that reads the following:

These are the main symptoms of cryptovirus because criminals only need your money. However, you should remove Pidon ransomware as soon as possible because of another feature – data stealing. These intruders can access any information stored on the machine in various files and stolen. Then, probably used in other scams or even sold on the dark web.

Experts[3] always state that it is not easy to perform manual Pidon ransomware removal due to all the files installed on the system and various features that malware disables. So rely on anti-malware tools like FortectIntego or SpyHunter 5Combo Cleaner and run a full system scan. This way, you can eliminate all the damage besides terminating the virus itself.

When it comes to data recovery and files encrypted by Pidon ransomware virus, we recommend relying on file backups or data recovery software. However, you can check the decryption options for this particular virus since researchers have a method of recovering data encrypted with offline keys. All these methods listed below.

Pidon ransomware virusPidon ransomware virus is a file-encrypting threat that appears on Windows computers and encrypts data.

Infected spam email file attachments may load malware on the system

Direct virus payload or malicious script designed to infect the system can get dropped on the targeted PC in various ways. One of the techniques involves software cracks, non-official software providers and malicious duplicates of applications. You can easily get malware if you get such products from the internet via torrents or p2p networks.

However, when it comes to ransomware the main spreading method is spam email campaigns and infected files that get attached to the legitimate-looking notifications posing as emails from services or companies like DHL, UPS, eBay and so on. You can allow malicious macros to get on your device by downloading the file and opening document or launching and executable without paying attention.

You should be aware that emails may have file attachments with malicious macros or direct malware, so make sure that the sender is familiar and think about the specific email when you receive it before opening the notification. If you are not using the service at the time or at all – delete the email once received and don't look back. Clean the email box more often and keep anti-malware tools running to avoid any cyber infections.

Pidon ransomware removal techniques

  • 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 Pidon ransomware;
  • Restore them.

Windows Previous Versions feature should help with file recovery:

If some of your data has been encrypted, you can use this third-party software to restore some individual files:

  • 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”.

Shadow Explorer might help you with restoring data:

If the ransomware virus did not delete Shadow Volume Copies of your encrypted data, you can use this software to recover some of your individual encrypted files:

Try using the Stop decrypter.

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

How to prevent from getting ransomware

Choose a proper web browser and improve your safety with a VPN tool

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.


Lost your files? Use data recovery software

While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.

To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
