Download and Run Emsisoft Decrypter for PClock (Quick Tutorial)

Date: February 7, 2026

What it does

Emsisoft Decrypter for PClock is a free tool from Emsisoft designed to attempt recovery of files encrypted by the PClock ransomware family when a removable weakness exists (e.g., known keys or specific implementation flaws).

Before you start (precautions)

• Do not modify encrypted files (don’t rename, move, or attempt other decryptors).
• Back up an encrypted sample set to a separate drive before attempting decryption.
• Run the tool on a clean system (scan with up-to-date antivirus) or an isolated environment.
• Decryption may not be possible for all infections; results depend on the ransomware variant and available keys.

Step-by-step quick tutorial

1. Download:
   • Visit Emsisoft’s official decryptor page (search “Emsisoft Decrypter PClock”) and download the PClock decryptor executable for Windows.
2. Verify:
   • Check the download source is Emsisoft’s domain and verify file hash if provided on the site.
3. Prepare:
   • Create a folder on the infected machine (or a clean recovery machine) and copy a few encrypted files plus their corresponding ransom note into it.
   • If possible, also copy the ransomware’s ransom note or any sample of the malware for reference.
4. Run as Administrator:
   • Right-click the downloaded decryptor and choose “Run as administrator.”
5. Load files:
   • Use the decryptor’s interface to point to the folder containing encrypted files (most Emsisoft decryptors auto-scan drives).
6. Start the process:
   • Click “Decrypt” (or equivalent). The tool will attempt to detect keys and decrypt files. Progress and results will display in the window and a log file will be saved.
7. Review results:
   • Check the log for success/failure messages. Successfully decrypted files will replace encrypted ones or be written alongside originals depending on the tool’s behavior.
8. If decryption fails:
   • Save the log and sample encrypted files. Check Emsisoft’s support page for updates or submit samples to Emsisoft for analysis.
9. Post-process:
   • Restore any remaining unrecoverable files from backups if available.
   • Reinstall OS or ensure the system is fully cleaned before reuse.

Troubleshooting common issues

• Tool won’t run: Ensure you have administrator rights and Windows Defender/AV isn’t quarantining it.
• No files decrypted: The variant may use strong keys; check for decryptor updates or submit samples.
• False positives by antivirus: Temporarily allow the tool from your AV vendor while scanning the file first.
