Lloo Virus Removal Guide (+Decrypt .lloo files)

Lloo – Ransomware

Lloo is a destructive software application working as typical ransomware. Michael Gillespie, the well-known virus researcher, very first found this new name in the DJVU ransomware family.

Lloo was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the encryption is effectively achieved, the users are unable to get access to them. Lloo virus adds its own “.lloo” to all the encrypted files. For instance, the file “price_list.xls”, as soon as crypted by Lloo, will be titled as “price_list.xls.lloo”. Once the file encryption is achieved, Lloo puts its own distinct text file (_readme.txt) into all the folders that keep the encrypted files.

The alert mentioned by text file asking for the random os really comparable to the notices given by other ransomware threats coming from the DJVU family. The warning basically indicates that the data has been secured and the only solution to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely true.

The technique to encrypt the files utilized by Lloo is not completely looked into. However, there is no doubt that each computer system owner might be provided a special decryption key, which is absolutely distinct. It is incredibly difficult to recuperate the data without the appropriate key in location.

“Don’t worry, you can return all your files!”, from text file message:

message from Lloo virus

One more peculiarity of the Lloo infection is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the crooks who have launched the Lloo infection into the internet. In order to get the key and bring back the crucial information, the users are told to connect with the scams via email or by telegram and to pay the ransom in the amount of $980.

The message likewise says that individuals need to get in touch with the Lloo authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so the people will get a 50% discount, for that reason, the ransom amount falls to $490.

No matter what the quantity of the ransom is, we highly recommend that you do not pay the ransom. There is no assurance that these online crooks will keep their promises, so they might not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. For this reason, paying ransom frequently does not lead to a successful recovery. So, the users might just lose their money for nothing.

Likewise, we advise you not to get in touch with the scams as they instruct. Do not transfer cash into their wallets. There are no applications that might split the Lloo virus or restore the data at no charge. Therefore, the only correct choice is to restore the data from possible backups (if available).
