Comodo Rescue Disk

Rescue disks are usually fit for situations when an infected PC cannot be cleaned by regular means, such as an antivirus scan or a dedicated removal tool. Designed by one of the most popular security companies, Comodo Rescue Disk is designed to allow the scan of an entire system and the removal of potential threats before booting into the installed operating system.

Like most rescue disk applications, Comodo Rescue Disk comes as an ISO image file that can be deployed on an external drive using a dedicated image mounting application.

Upon computer start, the user has to boot into Comodo Rescue Disk to be able to use it and initiate a scan for the local operating system, no matter the flavor (Windows or Linux).

Talking about the interface, you should keep in mind that there are two different starting modes for Comodo Rescue Disk, namely a graphic one and a text one. The difference between them is obvious but, in essence, the functionality is identical.

In text mode, all the options are displayed in a standard list, allowing users to control the navigation using the keyboard. Before starting, it is advisable to configure the network connection and go through the options to customize the way the system is analyzed.

Comodo Rescue Disk can run smart, full, or custom scans, each with its own disadvantages and perks. The detection algorithm tries to find changes in the system's MBR that might seem suspicious and can be configured to analyze archives.

Comodo Rescue Disk also comes with a heuristics scanner and logging capabilities. Items that are considered dangerous can be easily sent to the quarantine.

The utmost feature of Comodo Rescue Disk is that it allows users to launch antivirus scans in a pre-boot stage. In other words, it attempts to clean the system before the operating system loads. Thus, it can also be used in cases when the infection is preventing the OS from booting.
