Loading.STOP ransomware is the type of malware, whose main idea is to get users to pay ransom in the form of BitCoin to get their files back.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.Subnote: This article was last updated in September 2019, but we gave it an update in October 2019.

STOPDecrypter (STOP Ransomware) – Update September 2019As reported by Michael Gillespie, the operators of STOP ransomware have altered its code in newer versions.
These changes make the way the decrypter work impossible, starting with.coharos,.gero, and.hese. Apparently, the cybercriminals started to utilize proper asymmetrical encryption, meaning the offline keys will no longer be valid for decryption after the release of the final keys Gillespie extracted.The researcher is now working towards closing this decrypter, and continuing work on a new decrypter that will work only for the old versions of STOP (up to.carote). The new decrypter will completely replace STOPDecrypter once it’s released, and will work in a different way, the researcher said.This version of STOPDecrypter currently works for.nuksus,.cetori,.carote, and.stare files. It is designed to support specific offline IDs, so it may not be effective for all occasions of the various iterations of the ransomware.
Remove STOP RansomwareBe sure to only remove STOP once your files are decrypted. If the files are not decrypted, you should wait until security researchers update the decryptor to work for your variant. Until then, we strongly recommend that you backup your encrypted files and NOT pay the ransomware.
