ESET Win32/Virlock Cleaner: Step-by-Step Removal Guide for Infected PCs

How to Use ESET Win32/Virlock Cleaner to Remove Ransomware Safely

ESET Win32/Virlock Cleaner is a lightweight removal tool designed to detect and clean Virlock-type ransomware and related infections. Follow this step-by-step guide to remove ransomware safely, minimize data loss, and reduce the risk of reinfection.

Before you begin — precautions

• Disconnect from networks: Unplug Ethernet and disable Wi‑Fi to stop lateral spread and avoid contacting ransom servers.
• Work from a clean machine if possible: Download tools and read instructions on an uninfected computer, then transfer via USB if needed.
• Back up important files (read-only): If possible, make bit-for-bit disk images or copy unaffected files to an external drive that will remain offline afterward. Do not copy potentially encrypted or infected executables.
• Have recovery tools ready: Prepare a recovery drive or Windows installation media if you may need to repair or reinstall the OS.

Step 1 — Download ESET Win32/Virlock Cleaner safely

1. On a clean PC, visit ESET’s official support/download page. (Always prefer vendor sites to avoid fake tools.)
2. Download the Win32/Virlock Cleaner executable (or ESET’s removal tool package) and save to an external drive or the clean PC.

Step 2 — Boot the infected PC into Safe Mode (recommended)

Booting into Safe Mode reduces active malware processes and increases chances of successful removal.

• For Windows ⁄₁₁: Settings > Recovery > Advanced startup > Restart now > Troubleshoot > Advanced options > Startup Settings > Restart, then select Safe Mode (or Safe Mode with Networking if you must download updates).
• For older Windows: Press F8 during boot and choose Safe Mode.

Step 3 — Run ESET Win32/Virlock Cleaner

1. Insert the external drive (if used) and copy the cleaner to the infected PC.
2. Right‑click the executable and choose “Run as administrator.”
3. Allow the tool to update if prompted (requires internet).
4. Start a full system scan with the default cleaning actions. The tool will detect Virlock components, quarantine infected files, and attempt to repair altered system files.

Step 4 — Follow prompts and quarantined items review

• Review the scan log and quarantined items. ESET will usually quarantine or delete infected files and may attempt to restore altered file associations.
• If ESET marks critical system files as infected and offers repair, accept recommended repairs unless you have a specific reason not to.

Step 5 — Additional cleanup and verification

1. Reboot the system normally (not Safe Mode) and check functionality.
2. Run a second full scan with ESET or a complementary antimalware tool (e.g., Malwarebytes) to verify no remnants remain.
3. Check common persistence locations: Task Scheduler, Run/RunOnce registry keys, Startup folders, and services for unusual entries. Remove suspicious entries only if you know what they are; otherwise seek professional help.

Step 6 — Restore files safely

• If your files were encrypted and you have backups, restore from backups made before infection.
• Do not restore backups that may contain infected executables or scripts. Scan backups with ESET before restoring.
• If no clean backups exist and files are encrypted, consult reputable ransomware recovery resources and law enforcement; do not pay ransom without exploring all options.

Step 7 — Harden the system to prevent reinfection

• Install reputable antivirus/endpoint protection and keep it up to date.
• Apply all Windows updates and software patches.
• Enable a firewall and configure network segmentation where possible.
• Use strong, unique passwords and enable multi-factor authentication for remote access.
• Regularly back up data to offline or immutable storage and test restores.

When to seek professional help

• Ransomware persists after multiple removals.
• Critical business systems or large data sets are affected.
• You’re unsure about manually removing persistence mechanisms or restoring systems.
