To decrypt Rigd files, it’s recommended to seek and use alternative data-recovery techniques rather than pay the ransom. One possible alternative way to decrypt Rigd files is with the help of a free decryptor tool specifically designed to unlock data encrypted by Rigd. There are many Ransomware-decrypting tools on the Internet and most of them are free, but they are all specialized for a specific Ransomware threat (or several Ransomware variants that are similar to one another). To decrypt Rigd files with such a tool, you’d need one created specifically for this virus. Extracting older versions of your locked files from shadow copy system backups is another valid method that you can try as an alternative to the ransom payment. Whatever you decide to do, however, we strongly recommend that you only consider the payment variant as a last resort and even then only go for it if the files that got encrypted are worth the risk.
