From this note, we can learn, that malefactors offer to decrypt 1 file for free and can provide a “discount” if the user pays fast (within first 72 hours). Our experience and reports from multiple victims show, that those are false promises. Hackers rarely reply back after receiving the payment. However, do not despair – there are cases when your files can be decrypted. If during encryption process there was some internet connection loss or malfunction of hacker’s servers, STOP Ransomware uses an offline key, that can be retrieved by a special tool called STOPDecrypter. Please, download it below, and read instructions on how to use it carefully. If STOPDecrypter is unable to help you, you can try some alternative methods to restore your photos, documents, videos, etc. There are standard Windows system functions, such as restore points, the shadow copies, previous versions of files, can be useful, although, malicious algorithms often prevent such opportunities. Stellar Data Recovery Professional is one of the best file-recovery tools and, if used properly, may recover some copies of encrypted files, that were removed earlier. In this article, you will find complete instructions to remove STOP Ransomware and decrypt .nvetud, .zatrov, .lotej or .kovasoh files.

How STOP Ransomware infected your PC

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. 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.
