AVG Rescue CD is a comprehensive toolkit that will repair system crashes and return systems to a state where they can operate at full capacity, thanks to deep-rooted infections having been removed and file systems repaired.The AVG Rescue CD is provided in two versions: an ISO image that can be easily burned to an optical disc (CD), or a compressed version that can be installed to a bootable flash drive (USB). Once this is done, you can simply boot from the drive of choice directly to the AVG menu, where you can scan for viruses, edit files, test your drive, or even edit the registry. You can also access a number of common Linux tools to make changes to your system.
