Igvm Virus Removal Guide (+Decrypt .igvm files)

Igvm – Ransomware

Igvm is a harmful software application working as typical ransomware. Michael Gillespie, the popular virus researcher, very first found this new name in the DJVU ransomware family.

Igvm was developed for the sole purpose to encrypt all popular file types. Realistically, as soon as the file encryption is successfully achieved, the users are unable to get access to them. Igvm ransomware adds its own “.igvm” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Igvm, will be entitled as “price_list.xls.igvm”. As soon as the file encryption is achieved, Igvm puts its own distinct text document (_readme.txt) into all the folders that save the encrypted files.

The message specified by document requesting the random os extremely comparable to the notifications provided by other ransomware hazards belonging to the DJVU family. The warning basically indicates that the files have been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this declaration is definitely real.

The technique to encrypt the files used by Igvm is not entirely investigated. Nevertheless, there is no doubt that each computer owner may be released a special decryption key, which is absolutely distinct. It is incredibly tough to recover the information without the appropriate type in place.

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

Don't worry, you can return all your files! virus

One more peculiarity of the Igvm infection is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the total control by the criminals who have actually introduced the Igvm infection into the internet. In order to obtain the key and bring back the essential information, the users are told to connect with the scams by means of e-mail or by telegram and to pay the ransom in the quantity of $980.

The message also says that individuals need to contact the Igvm authors within 72 hours upon the minute of the information file encryption. The alert suggests that by doing so individuals will get a 50% discount, therefore, 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 crooks will keep their pledges, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts. For this reason, paying ransom often does not result in an effective recovery. So, the users might merely lose their money for nothing.

There are no applications that might crack the Igvm ransomware or bring back the data at no charge. Therefore, the only right choice is to restore the data from possible backups (if readily available).
