KRUU ransomware is a file-encrypting virus that locks your personal files and personal documents. KRUU ransomware requests bitcoin cryptocurrency to recover the encrypted files. The ransom charge varies from different versions of the KRUU ransomware.
KRUU ransomware encrypts files on your computer and adds a string of unique characters to the extension of the encrypted files. For example, image.jpg becomes image.jpg.KRUU
The decrypt text-file with instructions is placed on the Windows desktop: DECRYPT-FILES.txt
In most cases, it is not possible to recover the files encrypted by KRUU ransomware without the intervention of the Ransomware developers.
The only way to recover files infected by KRUU ransomware is to pay the ransomware developers. Sometimes it is possible to recover your files but this is only possible when the ransomware developers made a flaw in their encryption software, which unfortunately doesn’t occur frequently.
I do not recommend paying for the KRUU ransomware, instead, make sure you have a valid FULL back-up of Windows and restore it immediately.
Having said that there are no tools at this moment to restore your encrypted personal files or documents that are encrypted by the KRUU ransomware.
