How to remove KMA47 Ransomware and decrypt .encrypt files

What is KMA47 Ransomware

KMA47 was developed for the sole purpose – to encrypt personal data and demand money for its return. Such a virus falls into the category of high-risk ransomware infections. The process of data encryption starts with the addition of new .encrypt extension at the end of blocked files and finishes with the creation of read_me.txt – a ransom note explaining instructions on how to recover the files. For instance, a file like 1.pdf will change to 1.pdf.encrypt and reset its icon. KMA47 also changes victims’ wallpapers.

The note says victims got hacked by the virus resulting in full data encryption. In order to fix it, victims are guided to contact cybercriminals using e-mail communication (manager@mailtemp.ch or helprestoremanager@airmail.cc) and pay a ransom of 100$ eventually. After sending the money, ransomware developers should send your private key and special decryption software to unlock the data. Although cybercriminals might be the only figures able to fully decrypt your data, paying the ransom does not always guarantee you will get it eventually. Unfortunately, manual decryption is also less likely due to strong algorithms and online storage of keys. You can give it a try using third-party decryptors unless you have backup copies available. If you have spare files stored on the safe cloud or physical storage, copy them back and avoid paying the ransom. Note that prior to trying any of the recovery methods, it is important to remove the virus first. Otherwise, it may start the encryption again or spread to other systems working inside of the common network. Detailed instructions on how to remove KMA47 Ransomware and restore your data can be found in the tutorial below.

How KMA47 Ransomware infected your computer

Many ransomware infections use secretive methods to barrel their roots into a system. As a rule, cybercriminals disguise them as innocent attachments or links sent by ostensibly legitimate firms via e-mail. Users may be urged to open Word, Excel, JavaScript, PDF, or Executable files directly from the received message. The senders may say it is necessary to “View your shipment”, “Check Invoice”, “Collect the prize”, or something else with click-bait headings. Clicking on them will most likely lead to various infections like Trojans or ransomware designed to cause true chaos over your system. To stay protected against such distribution channels, it is important to not click on spam messages and not open their content inside. You should also avoid channels like backdoors, keyloggers, fake updates or software installers, web-injects, malicious ads, weak RDP configuration, and other frailties or vectors that could be exploited by different crooks.

How to protect computer from viruses, like KMA47 Ransomware, in future

1. Get special anti-ransomware software

Use ZoneAlarm Anti-Ransomware

ZoneAlarm Anti-Ransomware Dashboard

ZoneAlarm Anti-Ransomware Alert

ZoneAlarm Anti-Ransomware Blocked

Famous antivirus brand ZoneAlarm by Check Point released a comprehensive tool, that will help you with active anti-ransomware protection, as an additional shield to your current protection. The tool provides Zero-Day protection against ransomware and allows you to recover files. ZoneAlarm Anti-Ransomware is compatible with all other antiviruses, firewalls, and security software except ZoneAlarm Extreme (already shipped with ZoneAlarm Anti-Ransomware) or Check Point Endpoint products. The killer features of this application are: automatic file recovery, overwrite protection that instantly and automatically recovers any encrypted files, file protection that detects and blocks even unknown encryptors.

2. Back up your files

As an additional way to save your files, we recommend online backup. Local storage, such as hard drives, SSDs, flash drives, or remote network storage can be instantly infected by the virus once plugged in or connected to. KMA47 Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and a simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

Malicious attachments to spam or phishing e-mails are the most popular method of ransomware distribution. Using spam filters and creating anti-spam rules is good practice. One of the world leaders in anti-spam protection is MailWasher Pro. It works with various desktop applications and provides a very high level of anti-spam protection.
