Covm Virus Removal Guide (+Decrypt .covm files)

Covm Virus – Details

Covm is a malicious software application functioning as common ransomware. Michael Gillespie, the widely known virus researcher, very first discovered this new name in the DJVU ransomware family.

Covm was created for the sole function to encrypt all popular file types. Rationally, as soon as the encryption is effectively accomplished, the users are not able to get access to them. Covm ransomware includes its own “.covm” to all the encrypted data. For instance, the file “price_list.xls”, once modified by Covm, will be titled as “price_list.xls.covm”. When the encryption is accomplished, Covm puts its own special text file (_readme.txt) into all the folders that keep the encrypted files.

The message specified by _readme.txt requesting the random os very comparable to the alerts given by other ransomware dangers belonging to the DJVU family. The warning basically shows that the data has been encrypted and the only service to get access to it is to use a unique standalone key. Regretfully, this declaration is absolutely real.

The technique to encrypt the files utilized by Covm is not totally looked into. Nevertheless, there is no doubt that each computer owner may be released a special decryption key, which is absolutely special. It is exceptionally tough to recover the information without a suitable type in place.

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

message from Covm virus

One more peculiarity of the Covm 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 launched the Covm virus into the internet. In order to get the key and restore the essential data, the users are told to contact the scams through email or by telegram and to pay the ransom in the amount of $980.

The message also says that individuals should get in touch with the Covm authors within 72 hours upon the moment of the information encryption. The alert suggests that by doing so the people will get a 50% discount, for that reason, the ransom quantity falls 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 criminals 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. Hence, paying ransom frequently does not result in successful healing. So, the users might merely lose their money for absolutely nothing.

Similarly, we prompt you not to call the scams as they instruct. Do not transfer cash into their wallets. There are no applications that could split the Covm virus or restore the information for free. For that reason, the only correct choice is to restore the information from possible backups (if available).
