Kcvp Virus Removal Guide (+Decrypt .kcvp files)

Kcvp – General Info

Kcvp is a harmful software functioning as typical ransomware. Michael Gillespie, the widely known virus researcher, first found this new name in the DJVU ransomware family.

Kcvp was created for the sole purpose to encrypt all popular file types. Realistically, as quickly as the encryption is successfully achieved, the users are unable to get access to them. Kcvp ransomware adds its own “.kcvp” to all the encrypted data. For example, the file “price_list.xls”, when crypted by Kcvp, will be titled as “price_list.xls.kcvp”. When the file encryption is achieved, Kcvp puts its own special text file (_readme.txt) into all the folders that keep the encrypted files.

The message stated by _readme.txt asking for the random os extremely similar to the notices given by other ransomware dangers belonging to the DJVU family. The caution basically indicates that the data has been encrypted and the only service to get access to it is to use a special standalone key. Regretfully, this statement is absolutely true.

The technique to secure the files utilized by Kcvp is not completely investigated. However, there is no doubt that each computer owner may be released an unique decryption key, which is definitely special. It is very tough to recuperate the information without the proper type in place.

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

message from Kcvp virus

One more peculiarity of the Kcvp virus 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 crooks who have launched the Kcvp ransomware into the internet. In order to obtain the key and restore the important information, the users are informed 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 must call the Kcvp 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 rate, therefore, the ransom quantity drops down to $490.

No matter what the quantity of the ransom is, we strongly advise that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their promises, so they may not care at all what the victims feel about the encryption, even when the quantity of the ransom is received into their accounts. Thus, paying ransom frequently does not result in a successful recovery. So, the users might merely lose their money for nothing.

There are no applications that might crack the Kcvp virus or bring back the data at no cost. Therefore, the only correct decision is to bring back the data from possible backups (if available).
