How to remove crptrgr virus

Crptrgr virus is ransomware that encrypts your files, changes the filename, and adds .crptrgr to the file extension. The ransomware then leaves a note on the computer named “!Where_are_my_files!.html” that explains what happened to the files and demands a ransom payment of .5 bitcoins ($360 USD) in order to decrypt and recover your encrypted files.

Unfortunately, there is no solution to decrypt files encrypted by the crptrgr virus at this moment. We will keep this post updated if this changes in the future so make sure to bookmark this page. Even though there is not a solution, it is not suggested by the professional cyber security community to pay ransomware authors in order to retrieve your files unless you are completely out of options. Instead you can try to use programs like Shadow Explorer or Recuva to restore encrypted or deleted files.
