The Avast Decryption Tool for HiddenTear is a free utility designed to restore files compromised by the HiddenTear ransomware family without paying a ransom. 1. Preparation Actions
Isolate the PC: Physically disconnect the infected computer from the internet or local networks to prevent the malware from spreading.
Remove active malware: Run a comprehensive scan with a security program like Avast Antivirus to neutralize any active ransomware payloads.
Find a file pair: Locate one encrypted file and its exact, unencrypted original version (e.g., from a backup, an old email, or a default Windows wallpaper). This “known-plaintext” pair is mandatory for the tool to break the encryption key. 2. Download and Launch
Acquire the tool: Download the specialized HiddenTear utility from the official Avast Ransomware Decryption Tools portal or the No More Ransom Project.
Run as Administrator: Right-click the downloaded executable file (avast_decryptor_hiddentear.exe) and select Run as administrator.
Advance past welcome: Read the license agreement on the initial Wizard screen and click Next. 3. Target Selection
Choose drive paths: Select the specific folders, directories, or entire local disk drives containing your locked data.
Proceed: Click Next once all target locations are added to the list. 4. Break the Password
Input the file pair: When prompted by the password-cracking screen, provide the exact file path for your encrypted file alongside the path for its original copy.
Execute the crack: Click Start to initiate the key-recovery process. Note that this step demands significant processor power and might cause temporary system slowdowns.
Save the key: Once the algorithm successfully cracks the security string, click Next to load the key into the wizard. 5. File Recovery Execution
Enable backup safety: Check the Backup encrypted files box. This safety measure ensures you do not lose data if a system crash or power failure occurs during decryption.
Decrypt: Click the Decrypt button to safely restore your data back to its original state.
