Free W32/Piker Trojan Removal Tool — Quick Scan & Cleanup

If you suspect a W32/Piker Trojan infection, acting quickly reduces risk to your files and privacy. Below is a concise, step-by-step guide to safely scan for and remove W32/Piker using free tools and basic cleanup steps.

1. Prepare (before scanning)

• Disconnect: Unplug from networks or disable Wi‑Fi to prevent data exfiltration and lateral spread.
• Backup: Copy critical personal files (documents, photos) to an external drive that you will scan later. Do not back up executable files or installers.
• Safe Mode: Restart into Windows Safe Mode with Networking (press F8 or use Settings → Recovery → Advanced startup) to limit malware activity.

2. Recommended free tools

Use one or more of these reputable, free scanners:

• Microsoft Defender (built into Windows) — full offline scan available.
• Malwarebytes Free — excellent on‑demand scanner for trojans and PUPs.
• Kaspersky Virus Removal Tool (free) — thorough cleanup engine.
• ESET Online Scanner — good second opinion.

Use at least two different engines if possible for higher detection coverage.

3. Quick scanning steps

1. Update signatures: If online, update each tool’s virus definitions before scanning.
2. Run full/offline scan:
   • Microsoft Defender: Settings → Update & Security → Windows Security → Virus & threat protection → Scan options → Microsoft Defender Offline scan (restarts PC).
   • Malwarebytes: Open → Scanner → Scan.
   • Kaspersky/ESET: Run full system scan per their interface.
3. Quarantine or remove: Let the tool quarantine or delete detected W32/Piker files. Follow prompts to remove all flagged items.

4. Manual cleanup (if infections remain)

• Check startup entries:
  • Task Manager → Startup tab; disable suspicious entries.
  • Autoruns (Microsoft Sysinternals, free) for advanced cleanup — uncheck questionable autostart items.
• Inspect scheduled tasks: Task Scheduler → look for unknown tasks and disable/delete them.
• Browser cleanup: Reset browsers and remove unknown extensions.
• Delete temporary files: Run Disk Cleanup or use Settings → Storage to remove temp files.

5. Post‑cleanup verification

• Reboot into normal mode.
• Run a second scan with a different engine (e.g., run Malwarebytes if you used Defender first).
• Use an online scanner like VirusTotal to check suspicious single files before executing them.

6. Restore and harden

• Restore files: Only restore backups after scanning them with updated antivirus.
• Patch OS & apps: Install all recent Windows updates and software patches.
• Change passwords: After cleanup, change passwords for critical accounts (use a clean device if possible).
• Enable real‑time protection: Keep Microsoft Defender or another AV enabled for real‑time scanning.
• Enable automatic updates and consider using a reputable browser extension blocking scripts and ads.

7. When to seek professional help

• If malware persists after multiple scans and manual steps.
• If sensitive data may have been exposed (financial accounts, identity theft).
• If system files are heavily damaged or the OS won’t boot.
