Your files have been safely encrypted on this PC: photos, videos, documents, etc. Click “Show encrypted files” Button to view a complete list of encrypted files and you can personally verify this.

First of all, keep in mind that there is nothing safe about Cryptolocker-v3 virus. It uses RSA-2048 (a unique public key) to encrypt the files and urge you to pay 1 BTC, which is equal to $350 USD. No matter how disappointed you feel, we highly do not recommend paying the redeem. Even after paying the money files are not decrypted correctly and still cannot be opened successfully. Besides, when paying for the data, you are asked to disclose your banking information, which may encourage online scammers to steal money straight from your bank account. There are tens of ransomwares, including Threat Finder, FessLeak, CryptoWall and many others that are spreading on the Internet these days. In order to ensure the safety of your personal data, you should make backups for all the files and keep a reputable anti-spyware (e.g. Reimage) updated.
