How to remove [[email protected]].BAT Ransomware
As a rule, [[email protected]].BAT or BAT ransomware blocks victims from accessing their files stored on their computer. It is a part of Dharma Ransomware and encrypts the files by using RSA-1024 encryption. To get the files in its original decrypted form, victims are urged to buy a decryption key from the crooks behind this. For this purpose, the ransomware generates a ransom note in a file named “RETURN FILES.txt” that appears soon after the files get encrypted and shows a pop-up Window. The encrypted files will have a unique extension name .bat including with victims’ ID and email address of the developers, which is [[email protected]].
More about the ransom note

The ransom note states that, in order to decrypt the files, the victims must need to purchase a decryption tool. For this, first thing is required is to contact the developers from the provided email address and send the ID that is provided to each victim. Suppose, a victim sends his ID to the provided email address. Later on, a Window pop-up will appear on the computer screen that has written Cryptowallet address of the developers. According to the developers, once paid the Bitcoin, the victim will get a unique decryption tool follow with detail instruction how to use it.
The Cyber criminals here states that on the ransom note that, the victims should pay the ransom within 7 days after that the decryption tool might be overwritten. In other word, after the mentioned day, the victims will not be able to get their files back. In order to gain the trust of the victims and make them believe on their decryption tool that it really works, the developers often offer decryption of three decrypted files less than 1 MB for free. They often threaten not to use any decryption software otherwise the decryption would be impossible after that.
Remember, these all are nothing but a trick that Cyber criminals use that create a condition to the victims to pay them ransom fee. There are many cases where no any decryption tool is provided to victims even if they fulfill all their demand. Thus, you should avoid paying the ransom fee in any worst condition.
