What is STOP Ransomware
If you cannot open your files and they’ve got .repl, .kuus, .maas or .zida extensions added at the end of the filenames, it means your PC is infected with STOP/Djvu Ransomware. This malware is tormenting its victims since 2017 and already became the most wide-spread ransomware-type virus in history. It infects thousands of computers per day using various methods of distribution. It is using a complex combination of symmetric or asymmetric encryption algorithms, removes Windows restore points, Windows previous versions of files, shadow copies and basically leaves only 3 possibilities for recovery. First is to pay the ransom, however, there is absolutely no guarantee, that malefactors will send the decryption key back. The second possibility is very unlikely, but worth trying – using special decryption tool from Emsisoft, called STOP Djvu Decryptor. It works only under a number of conditions, that we describe in the next paragraph. The third one is using file-recovery programs, that often act as a workaround for ransomware infection problems. Let’s observe the ransom note file, that the virus places on the desktop and in the folders with encrypted files.

How STOP Ransomware infected your PC
Malicious software created using the STOP virus gets four files when it enters a computer. One of them provokes the appearance of a fake message about Windows system updates. In this way, it lulls the user’s alertness. Cybercriminals do not name the cost of decryption but promise to make a discount if the user in the near future turns to them for help.
It uses rdpclip.exe to replace a legal Windows file and to launch an attack on a computer network. After encrypting the files, the encrypter is deleted using the delself.bat command file. STOP Ransomware virus is propagated via spam attack with malicious e-mail attachments and using manual PC hacking. It can be distributed by hacking through an unprotected RDP configuration, fraudulent downloads, exploits, web injections, fake updates, repackaged, and infected installers. Virus assigns certain ID with the victims, that is used to name those files and supposedly to send decryption key. Great tools to protect against STOP Ransomware are: Emsisoft Anti-Malware and Malwarebytes Anti-Malware.

2. Back up your files
As an additional way to save your files, we recommend online backup. Local storages, such as hard drives, SSDs, flash drives or remote network storages can be instantly infected by the virus once plugged in or connected to. STOP 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 simple interface. You can read more about iDrive cloud backup and storage here.
3. Do not open spam e-mails and protect your mailbox
