CryptoPatronum ransomware removal instructions
What is CryptoPatronum?
CryptoPatronum was discovered by Amigo-A. Like most programs of this type, this ransomware is designed to block access to data by encrypting it. Also, it changes names of all encrypted files by adding the "email@example.com" email address and appending the ".enc" extension to their filenames. For example, CryptoPatronum renames "1.jpg" to "firstname.lastname@example.org", and so on. Additionally, it creates a text file (ransom note) named "HOW TO RECOVER ENCRYPTED FILES.txt".
As stated in the "HOW TO RECOVER ENCRYPTED FILES.txt" text file, victims should send cyber criminals an email with the appointed personal identifier (ID) in it to email@example.com. Also, they can attach up to three encrypted files to it, CryptoPatronum's developers offer to decrypt those files for free. However, the rest of encrypted files can be decrypted only with a decryption software and key that can be purchased for 1 BTC (Bitcoin) or 50 ETH (Ethereums). A payment must to be made by transferring cryptocurrency to one of the provided addresses. There are no free tools that could be capable of decrypting data encrypted by CryptoPatronum, at least not at the moment. In other words, these cyber criminals are the only ones who have tools that can decrypt files encrypted by their ransomware. However, it is very common that cyber criminals do not send decryption tools even if victims pay them. There are many cases where victims who trusted ransomware developers got scammed. Since there are no free tools that could decrypt files encrypted by CryptoPatronum, the only way to recover them without losing money is to restore them from a backup. Also, it is worth mentioning that files remain encrypted even after uninstallation of ransomware. By removing ransomware from the operating system victims only prevent it from causing further encryptions.

AlphaBetaCrypt, LIVE and Reha are a couple of examples of other ransomware. What most programs of this type have in common is that they make sure that victims could not access their data by encrypting it and create and/or display a ransom note. Typically, the only main differences are price of a decryption software and/or key and cryptographic algorithm (symmetric or asymmetric) that ransomware uses to encrypt files. In most cases it is impossible to decrypt file without having to use tools that can be purchased only from cyber criminals who designed ransomware. It can be avoided only if ransomware is not finished (has bugs, flaws) and/or if a victim has a data backup. Therefore, we recommend to always have a backup and keep it on a remote server and/or unplugged storage device.

How to protect yourself from ransomware infections?
We strongly recommend not to open attachments (or web links) that are attached to irrelevant emails, especially if they are received from unknown, suspicious addresses. It is worth mentioning that these emails usually are disguised as important, official, and so on. Also, it is important to update and activate installed software through implemented functions or tools that are designed by official developers. Third party software like unofficial activation tools are not legal. Files and programs should be downloaded only from official websites and via direct download links. None of the sources that are mentioned in the paragraph above should be trusted. It is any less important to regularly scan the operating system for threats with a reputable anti-virus or antispyware suite and allways remove detected threats as soon as possible. If your computer is already infected with CryptoPatronum, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining CryptoPatronum ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of CryptoPatronum are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
