There's a start menu, desktop items for other tools like GParted, a file browser, and of course a shortcut to ESET SysRescue.

This tool provides a full desktop environment, so if you're uncomfortable with text-only user interfaces, you should be okay with how this one works. It comes from the company ESET, which also sells security software for home users and businesses. It's a plus that Comodo Rescue Disk includes a familiar Desktop-like interface because it makes it easier to use than some of these other text-based scanning tools.ĮSET SysRescue is another bootable virus scanner that you can use for free from a CD, DVD, or USB device. You can also scan archives, enable heuristics scanning, and skip files over a specified size.

A custom scan lets you choose individual files and folders to scan instead of an entire drive. Smart scan checks for viruses and rootkits in the memory, boot sectors, autorun entries, and other areas like the registry and system folder. There are three different scan types: smart scan, full scan, or custom scan. The GUI version has a familiar program interface which is much easier to use.

In addition to the regular, installable Comodo Antivirus software, Comodo also has a free bootable antivirus program.Ĭomodo Rescue Disk can be launched from a USB device or disc in either text-only mode or with a full graphical user interface (GUI).
