Iisa Virus Removal Guide (+Decrypt .iisa files)

Iisa Virus – Details

Iisa is a destructive software application functioning as typical ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.

Iisa was developed for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is successfully achieved, the users are unable to get access to them. Iisa ransomware adds its own “.iisa” to all the encrypted files. For instance, the file “price_list.xls”, when modified by Iisa, will be titled as “price_list.xls.iisa”. As soon as the encryption is achieved, Iisa puts its own unique text file (_readme.txt) into all the folders that store the encrypted files.

The message stated by text file requesting for the random os really comparable to the notifications given by other ransomware dangers belonging to the DJVU family. The warning basically indicates that the data has been encrypted and the only solution to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely real.

The method to secure the files utilized by Iisa is not totally investigated. Nevertheless, there is no doubt that each computer system owner may be provided a special decryption key, which is definitely unique. It is very tough to recuperate the information without the appropriate key in location.

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

One more peculiarity of the Iisa virus is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the crooks who have actually introduced the Iisa ransomware into the world wide web. In order to obtain the key and restore the important data, the users are told to connect with the scams through e-mail or by telegram and to pay the ransom in the quantity of $980.

The message likewise states that the people need to get in touch with the Iisa authors within 72 hours upon the moment of the information encryption. The alert shows that by doing so individuals will acquire a 50% discount, for that reason, the ransom quantity drops down to $490.

No matter what the quantity of the ransom is, we highly advise that you do not pay the ransom. There is no assurance that these online scoundrels 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 gotten into their accounts.

For that reason, the only right decision is to restore the information from possible backups (if available).
