Happychoose ransomware removal instructions
What is Happychoose?
Happychoose is a part of GlobeImposter ransomware family. Typically, software of this type encrypts files, changes their filenames and creates some ransom note. Happychoose renames files by appending the ".happychoose" extension to their filenames. For instance, it changes "1.jpg" to "1.jpg.happychoose", and so on. It also creates the "Decryption INFO.html" file (ransom note) and drops it in every folder that contains encrypted data.
As explained in the "Decryption INFO.html" ransom note, encrypted files can be decrypted with a certain decryption tool. In order to get instructions on how to buy it victims have to send one encrypted image or text file to email@example.com or firstname.lastname@example.org and provide the assigned ID. After that Happychoose's developers supposed to send decrypted file, name the price of a decryption tool and provide instructions on how to pay for it. Also, victims are warned not to try to remove the program (ransomware), run any antivirus tools or try to decrypt files by themselves because it will permanently damage encrypted files. It is common that victims who pay a ransom get scammed. In other words, they do not receive decryption tool and/or key even if they have paid for it. Therefore, cyber criminals behind ransomware-type programs should not be trusted. Unfortunately, ransomware is a type of software that usually is designed to encrypt data with a strong encryption algorithm and its developers are the only ones who have tools that can decrypt encrypted files. In most cases the only way to recover files without their tools is to restore them from a backup. It is worthwhile to mention that files remain encrypted even if victims uninstall ransomware from the operating system. However, its removal prevents if from causing further encryptions.

In most cases malicious programs like Happychoose are all very similar. A couple of examples of other ransomware are MARRACRYPT, Jerry_glanville and MaMo434376. As a rule, they encrypt data create and/or display a ransom note. Two main variables usually are cryptographic algorithm (symmetric or asymemtric) that ransomware uses to encrypt files and the price of a decryption tool and/or key. It is possible to decrypt files without having to use tools that only cyber criminals have when ransomware is not ideally programmed: has some bugs, flaws. Unfortunately, it is not a common case. In most cases data recovery from a backup is the only way to restore files for free, therefore, data should be always backed up and kept on a remote server and/or unplugged storage device.

How to protect yourself from ransomware infections?
Emails that are irrelevant, contain attachments (and/or website links), and are received from unknown, suspicious address should not be trusted. Quite often such emails are sent by cyber criminals and used to proliferate malware. All installed software must be updated with implemented functions and/or tools that are designed by official software developers. Software (and files) should be downloaded from trustworthy, official websites, and via direct links. Various third party downloaders, installers, questionable pages and other similar sources are often used to proliferate unwanted, potentially malicious software. Unofficial activation ('cracking') tools are often used to distribute malware as well, therefore, they should never be used to activate any software. Besides, it is not legal to bypass activation of licensed programs by using unofficial tools. One more way to keep computers safer is to have a reputable anti-spyware or antivirus software installed on them and regularly scan operating system for threats. If your computer is already infected with Happychoose, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Happychoose ransomware virus infiltrating your PC).
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 Happychoose 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 Happychoose 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.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Happychoose ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites, and Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
