Below is a comprehensive guide covering preparation, detection, manual and automated removal, cleanup, prevention, and recovery. Follow the steps carefully and pause if you’re unsure — some removal actions (like deleting system files or editing the registry) can cause system issues if done incorrectly. If you have critical data, back it up before making system changes.

Before you begin — Preparation and safety

  • Backup your important files. Use an external drive or a cloud service to copy documents, photos, and other irreplaceable data. If the system is compromised, backups ensure you won’t lose data during cleanup.
  • Disconnect from the internet (temporary). This prevents the malware from communicating with remote servers or spreading across your network. Reconnect only when you need to download tools or updates.
  • Have a secondary device ready. Use another computer or phone to download removal tools, look up instructions, or seek help if the infected machine becomes unstable.
  • Make a system restore point (Windows). If your OS supports it, create a restore point so you can roll back changes if something goes wrong.
  • Note suspicious behavior. Write down filenames, error messages, unusual processes, or changed settings — these clues help during removal and when scanning.

Step 1 — Identify whether BadBlocked FileCopier is present

  • Check running processes:
    • Windows: Open Task Manager (Ctrl+Shift+Esc) → Processes tab. Look for unusual names like FileCopier, BadBlocked, or anything unfamiliar using high CPU/disk.
    • macOS: Open Activity Monitor → CPU/Memory tabs.
    • Linux: Use top or htop.
  • Check installed programs:
    • Windows: Settings → Apps → Apps & features (or Control Panel → Programs and Features) and look for recently installed or suspicious entries.
    • macOS: Look in /Applications and check LaunchAgents/LaunchDaemons (~/Library/LaunchAgents, /Library/LaunchAgents, /Library/LaunchDaemons).
  • Check startup entries:
    • Windows: Task Manager → Startup tab, or use Autoruns (sysinternals) to see everything that runs on boot.
    • macOS: System Settings → Login Items, plus the LaunchAgents/Daemons folders.
  • Inspect network activity:
    • Use Resource Monitor (Windows) or lsof/netstat/Activity Monitor (macOS) to see connections from suspicious processes.
  • Check for newly created files/folders:
    • Look in common temp and user folders (Windows: %TEMP%, %APPDATA%, %LOCALAPPDATA%; macOS: /tmp, ~/Library/Application Support).
  • Scan with reputable antivirus/antimalware tools (see Step 3 list for suggestions).

If you find clear traces (process names, files, startup entries) that match BadBlocked FileCopier or behavior that looks malicious (unexpected copying of files, pop-ups, blocked access), proceed to removal.

Step 2 — Isolate and contain

  • Disconnect the infected machine from other devices and shared network drives.
  • If the machine is a server or stores sensitive data, consider powering it down and working from a forensic image or a clean environment to avoid further spread.
  • If you must keep it online to download tools, connect only to a trusted network and enable a local firewall rule to block suspicious outbound connections.

Step 3 — Automated removal with reputable tools

Using trusted anti-malware tools is the safest first-line removal. Below are recommended types of tools and example names (choose the tool you trust or that is appropriate for your OS):

  • Real-time antivirus (perform a full system scan)
    • Windows: Microsoft Defender (built-in), or a third-party AV like Bitdefender, Kaspersky, ESET.
    • macOS: Malwarebytes for Mac is commonly used for PUPs and malware.
  • On-demand scanners and removal tools:
    • Malwarebytes (Windows/macOS) — effective at removing PUPs and adware.
    • HitmanPro (Windows) — good second-opinion scanner.
    • ESET Online Scanner (Windows) — deep scan capability.
    • Windows Defender Offline scan — boots into a special environment to remove persistent threats.
  • Rootkit scanners (if you suspect deep persistence)
    • Windows: Malwarebytes Anti-Rootkit (Beta), Kaspersky TDSSKiller.
    • Linux/macOS: chkrootkit, rkhunter (for Linux); rootkits are rarer on macOS but check with OS-specific tools.

Automated removal steps:

  1. Update the tool’s definitions.
  2. Run a full system scan (not just quick).
  3. Quarantine/remove detected items.
  4. Reboot if prompted.
  5. Run a second scan with a different reputable tool to confirm removal.

Step 4 — Manual removal (advanced; proceed cautiously)

If automated tools can’t fully remove BadBlocked FileCopier, manual steps help remove leftover files, services, or registry entries. Only perform these if you’re comfortable with system internals.

Windows manual removal checklist:

  • Stop the suspicious process:
    • Task Manager → End task. If it respawns, boot into Safe Mode (see below).
  • Remove startup entries:
    • Use Autoruns (Microsoft Sysinternals) — uncheck and delete suspicious entries, note their file paths.
  • Delete files:
    • Navigate to the file paths shown by Autoruns or Task Manager and delete the executable and related files (often in %APPDATA%, %LOCALAPPDATA%, or Program Files).
  • Clean registry entries:
    • Run regedit; search for the program name, executable name, or publisher. Backup registry before deleting keys.
  • Remove services:
    • Open Services.msc, find suspicious services, stop them, then set startup type to Disabled and delete via sc delete from an elevated command prompt.
  • Clear scheduled tasks:
    • Task Scheduler → Task Scheduler Library — look for tasks created by the malware and delete them.
  • Safe Mode:
    • Boot Windows into Safe Mode (or Safe Mode with Networking if you need internet) to remove files that resist deletion.

macOS manual removal checklist:

  • Quit suspicious processes in Activity Monitor.
  • Remove Login Items and entries in LaunchAgents/LaunchDaemons:
    • Check ~/Library/LaunchAgents, /Library/LaunchAgents, /Library/LaunchDaemons for suspicious .plist files and remove them.
  • Delete application bundles from /Applications or ~/Applications.
  • Remove related files from ~/Library/Application Support and ~/Library/Preferences.
  • Empty Trash and reboot.

Linux manual removal checklist:

  • Identify and kill suspicious processes (ps aux | grep name; kill -9 PID).
  • Remove startup scripts (systemd: systemctl disable –now service; init scripts in /etc/init.d).
  • Remove binaries from /usr/local/bin, /opt, or home directories.
  • Check crontab for entries created by the malware (crontab -l and /etc/cron.*).

Step 5 — Clean residual effects

  • Clear browser caches, extensions, and reset browser settings if the malware affected web browsers.
  • Delete temporary files:
    • Windows: Disk Cleanup or manually clear %TEMP% and browser caches.
    • macOS/Linux: Clear /tmp and application caches.
  • Check permissions:
    • Ensure that file and folder permissions weren’t changed. Restore defaults if needed.
  • Check scheduled tasks and startup again to verify nothing was missed.
  • Examine recent system logs for clues (Windows Event Viewer; macOS Console; Linux syslog).

Step 6 — Verify and monitor

  • Run multiple scans with different reputable tools to confirm no remaining traces.
  • Monitor system behavior for a few days: CPU/disk/network usage, unusual pop-ups, or unexpected file changes.
  • Use Autoruns/LaunchAgents and Task Manager/Activity Monitor periodically to confirm no reappearance.

Step 7 — Recovery and restoring data

  • If files were corrupted or missing:
    • Restore from your clean backup.
    • Use file-recovery tools only if backup isn’t available (Recuva, PhotoRec). Recovery success varies and might risk restoring infected files—scan recovered files before opening.
  • If system stability is compromised:
    • Consider a clean OS reinstall. For Windows, reset or reinstall; for macOS, reinstall macOS from Recovery; for Linux, reinstall the distribution.
  • If the system hosted sensitive credentials (passwords, SSH keys, banking info), assume compromise and rotate passwords from a known-clean device. Revoke and reissue keys or certificates if necessary.

Prevention — Hardening to avoid reinfection

  • Keep your OS and software up to date; enable automatic updates where practical.
  • Use reputable antivirus with real-time protection and keep definitions current.
  • Practice safe downloading: avoid unknown download sites, don’t open attachments from untrusted emails, and verify installers with checksums where possible.
  • Use least-privilege accounts — don’t run day-to-day work as an administrator.
  • Regularly back up data offline or to a trusted cloud provider with versioning.
  • Educate users on phishing and social engineering risks.
  • Employ network protections: firewall, DNS filtering (e.g., block known-malicious domains), and segmentation for sensitive systems.

When to seek professional help

  • If the malware persists after automated and manual removal attempts.
  • If sensitive data was exposed or stolen (financial, personal identity, corporate secrets).
  • If a server or multiple machines were affected in a business environment.
  • If you lack confidence editing system files or the registry.

Professional incident response can preserve forensic evidence, fully eradicate threats, recover data, and harden systems.

Quick checklist (summary)

  • Backup important data.
  • Disconnect from network and isolate the device.
  • Run full scans with at least two reputable antimalware tools.
  • Use Safe Mode and Autoruns to remove persistent startup entries.
  • Manually delete files, services, scheduled tasks, and registry/launch entries if needed.
  • Re-scan and monitor for recurrence.
  • Restore from backups or reinstall OS if necessary.
  • Rotate credentials and harden the system to prevent reinfection.
