How to remove Aamv Ransomware and decrypt .aamv files

0
Aamv is a new ransomware variant developed and published by a fraudulent group named Djvu. Being a file-encrypting virus, it blocks access to personal data by using secure encryption algorithms. This means that files stored on a PC will no longer be opened by users until they are decrypted. In order to show that all files have been put under a lock, developers append the new .aamv extension to each of the files. For instance, a file sample like 1.pdf will change to 1.pdf.aamv and reset its icon eventually. After this part of encryption is finished, the virus creates a text note (_readme.txt) with ransom instructions.

If your files became no longer accessible and now appear with the new .MEOW extension, then you are most likely infected with Meow Ransomware (a.k.a. MeowCorp2022 Ransomware and ContiStolen Ransomware). This file-encryptor blocks access to practically all types of system-stored data using the ChaCha20 algorithm and demands victims to establish contact with its developers (presumably to pay for decryption). In addition, it was also determined that this ransomware works on code stolen from another popular file-encryptor named Conti-2 Ransomware. Information about contacting swindlers can be found inside a text note called readme.txt, which the virus drops into each folder with encrypted files.

How to remove Loplup Ransomware and decrypt .loplup files

Loplup is a file-encrypting virus that was determined to be part of the ZEPPELIN ransomware family. While restricting access to system-stored data, it renames attacked files by adding the custom .loplup.[victim's_ID] extension. This means a file previously called 1.pdf will change to something like 1.pdf.loplup.312-A1A-FD7. Note that the victim's ID is variable so it can be different in your case. Following successful encryption of data, Loplup creates a text file (!!! ALL YOUR FILES ARE ENCRYPTED !!!.TXT) that contains decryption guidelines.
