Qall Virus Removal Guide (+Decrypt .qall files)

Qall – General Info

Qall is a malicious software working as typical ransomware. Michael Gillespie, the well-known malware researcher, very first found this new name in the DJVU ransomware family.

Qall was developed for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively accomplished, the users are unable to get access to them. Qall virus adds its own “.qall” to all the encrypted files. For example, the file “price_list.xls”, as soon as crypted by Qall, will be entitled as “price_list.xls.qall”. When the encryption is achieved, Qall puts its own distinct text document (_readme.txt) into all the folders that save the encrypted files.

The message mentioned by _readme.txt asking for the random os extremely comparable to the alerts offered by other ransomware hazards coming from the DJVU family. The caution basically shows that the data has been secured and the only solution to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.

The approach to secure the files utilized by Qall is not totally looked into. Nevertheless, there is no doubt that each computer system owner might be released an unique decryption key, which is absolutely distinct. It is extremely hard to recuperate the information without the appropriate type in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

One more peculiarity of the Qall infection is that the users are not able to get access to the key. The decrypting key is hosted on an unique server under the total control by the criminals who have actually released the Qall infection into the internet. In order to get the key and restore the crucial data, the users are informed to contact the scams via email or by telegram and to pay the ransom in the quantity of $980.

The message also states that individuals ought to contact the Qall authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so the people will obtain a 50% discount, for that reason, the ransom amount drops down to $490.

No matter what the quantity of the ransom is, we strongly encourage that you do not pay the ransom. There is no warranty that these online scoundrels will keep their guarantees, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. Thus, paying ransom typically does not lead to an effective healing. So, the users may just lose their money for nothing.

Similarly, we prompt you not to get in touch with the frauds as they advise. Do not move cash into their wallets. There are no applications that might split the Qall ransomware or restore the data for free. Therefore, the only proper decision is to bring back the information from possible backups (if offered).
