Iswr Virus Removal Guide (+Decrypt .iswr files)

Iswr – General Info

Iswr is a malicious software functioning as typical ransomware. Michael Gillespie, the well-known virus researcher, first found this new name in the DJVU ransomware family.

Iswr was developed for the sole function to encrypt all popular file types. Logically, as quickly as the encryption is effectively achieved, the users are unable to get access to them. Iswr virus includes its own “.iswr” to all the encrypted data. For example, the file “price_list.xls”, as soon as crypted by Iswr, will be titled as “price_list.xls.iswr”. As soon as the file encryption is achieved, Iswr puts its own special text document (_readme.txt) into all the folders that store the encrypted files.

The alert stated by document asking for the random os very similar to the alerts offered by other ransomware risks belonging to the DJVU family. The warning basically shows that the data has been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this declaration is absolutely true.

The technique to encrypt the files utilized by Iswr is not entirely investigated. Nevertheless, there is no doubt that each computer system owner may be issued an unique decryption key, which is absolutely unique. It is extremely tough to recuperate the data without the proper type in location.

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

One more peculiarity of the Iswr virus is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have actually launched the Iswr virus into the internet. In order to get the key and bring back the important information, the users are informed to get in touch with the scams through email or by telegram and to pay the ransom in the amount of $980.

The message likewise states that individuals need to call the Iswr authors within 72 hours upon the moment of the information encryption. The alert shows that by doing so individuals will obtain a 50% discount, therefore, the ransom amount falls 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 crooks will keep their guarantees, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is gotten into their accounts. For this reason, paying ransom frequently does not result in an effective recovery. So, the users may merely lose their money for nothing.

Likewise, we advise you not to contact the scams as they instruct. Do not transfer loan into their wallets. There are no applications that could split the Iswr ransomware or restore the information at no charge. Therefore, the only proper choice is to restore the information from possible backups (if readily available).
