The .qwerty file virus is a specific kind of malware aims to encrypt files bearers of valuable information stored on the compromised host. After encryption, the access to all encrypted files is wholly restricted and they are marked with the .qwerty file extension.

In general, hackers want to blackmail you into transferring them a ransom of 0.05 BTC to their Bitcoin address. However, there is no guarantee that they will provide you a working solution for your .qwerty files even if you pay the ransom. It’s better to ignore their menaces and overcome the problem by the help of alternative ways. Thereby you will stay away from further financial and privacy abuses.

→.tx, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .odt, .png, .csv, .sql, .mdb, .php

The researcher has found that on the current stage of .qwerty ransomware development the locked .qwerty files can be decrypted by the HiddenTear Decrypter tool. Before you proceed with the restore process, you should be sure to have a backup of all .qwerty files on an external drive.
