Comodo Rescue Disk is a free bootable malware-removal tool for Windows systems. It runs Comodo Cleaning Essentials in a lightweight Linux-based pre-boot environment, allowing users to scan and clean infections before Windows loads. That positioning suits cases where malware prevents startup or regular antivirus software cannot remove an infection. Users can create the rescue disk on an ISO, CD/DVD, USB, or another drive, then choose graphical or text scanning modes.

Its main strength is scan flexibility. Smart Scan checks critical areas and boot sectors, Full Scan covers files across all drives, and Custom Scan allows the scope to be tailored. The tool also supports threat cleaning and quarantine, with options to delete or restore quarantined files. An embedded file manager, terminal, browser, and screenshot utility add practical tools inside the rescue environment, particularly when normal Windows access is disrupted.

Comodo Rescue Disk is most appropriate for Windows users who need a free, manual, offline recovery option rather than an always-on security suite. Remediation actions are user-directed, so it fits people comfortable choosing scan scopes and deciding whether to quarantine, delete, or restore files. Its Windows-only platform and pre-boot workflow make it less suitable for multi-platform coverage or routine automated protection. The product documentation identifies the rescue disk as version 2.0, another reason to view it as a focused recovery utility rather than a broad malware-management platform.
