br br If you have not stored copies of your most valuable personal files in a secure location (e.g., removable hard drive), you are in trouble. It takes one careless move for Ninja Ransomware to enter your PC, and when it does, it encrypts your personal files to have leverage when asking for a ransom payment. Even if you pay the demanded sum of money, there are no guarantees that your files will be decrypted, which is why you have to be extremely careful with Ninja Ransomware. If your files are backed up, remove Ninja Ransomware as shown in the video. Should you have more questions, post them in the comments box.
