Kaspersky RectorDecryptor is a free, specialized utility developed by Kaspersky Lab to decrypt user files locked by the Trojan-Ransom.Win32.Rector malware family. This ransomware targets critical file types—such as .jpg, .doc, .pdf, and .rar—and appends distinct extensions while demanding a ransom payment. Key Capabilities of RectorDecryptor
The utility acts as a specialized reverse-engineering tool to break the encryption applied by the Rector malware.
Target Extensions: It reverts files altered with known Rector signatures like .vscrypt, .infected, .bloc, and .korrektor.
File Cleanup: It features an optional setting to safely purge residual, locked copies of your files once verified decryptions are complete.
Logging: It generates a comprehensive system drive report detailing the success metrics of the recovery process. Step-by-Step Ransomware Removal & Decryption Guide
Never run a decryptor tool before purging the active virus from your system, as active ransomware will simply re-encrypt your newly recovered files. Follow this chronological deployment: Step 1: Isolate the Threat
Disconnect the device physically and electronically from Wi-Fi, Ethernet, and local networks to prevent the virus from spreading to secondary network drives.
Unplug external storage devices, flash drives, and backup enclosures. Step 2: Remove the Active Ransomware
Download a trusted anti-malware solution, such as the Kaspersky Free Virus Removal Tool or Kaspersky Premium using an uninfected device. Reboot your compromised machine into Safe Mode.
Run a complete system scan to identify, isolate, and safely delete the Rector Trojan executable. Step 3: Run Kaspersky RectorDecryptor
Download the executable file directly via the official Kaspersky Free Recovery Tools Portal.
Launch RectorDecryptor.exe on the disinfected machine and accept the standard License Agreement. Click the Change parameters link prior to starting.
Check the box labeled Delete crypted files after decryption if you want the tool to automate space cleanup. If you want to keep the locked variants as backups until you verify everything works, leave this box unchecked. Click OK.
Consolidate your encrypted files into single folders to speed up processing.
Click Start scan and point the program file-explorer toward the targeted folders.
Review the session performance logs generated directly in your system drive root (C:\RectorDecryptor.Tool_Version_Log.txt).
