How to remove PDF ransomware and decrypt .[decryptbots@cock.li].pdf files

PDF ransomware encryption process

PDF is a new member of the well known family of ransomware viruses called Dharma. The aim of this software is to change the structure of your files (encrypt) in order to make you pay for restoring these files (decryption). As I’ve already mentioned, the reason to make such viruses is your money, that’s why it’s important to infect your device without noticing. Hackers usually use fake emails, to be more exact, attachments to achieve this aim. As you open such an attachment, your device is infected. Then PDF ransomware searches for suitable files, it is .doc, .xls, .wps, .docm, .docx, .jpg, .png and other types of documents and media files. When searching is done, the virus begins to encrypt these files. After it, these files are unreadable, as the extensions (structure) have been changed to .[decryptbots@cock.li].pdf. Don’t try to remove PDF ransomware encryption by the renaming of files, it can break them at all. When everything is done, the virus creates a special ransom note with the contacts and price for “services”:
