The F-Secure Rescue CD is a free tool you can use to fix a computer that no longer starts because the operating system has been corrupted by malware. For more advanced users, Rescue CD enables other kinds of repair and data recovery operations as well.
Rescue CD contains a Knoppix (a kind of Linux) operating system which allows using your Windows PC and getting access to the hard disks. It scans the computer and renames all files containing malware to .virus file extension. Virus definition databases are updated automatically if the computer has an Internet connection.
The new utilities on the CD are:
- PhotoRec is a tool that can be used to recover data that has been accidentally deleted or lost due to a corrupted file system on a disk.
- TestDisk is another data recovery tool that can be used to recover a lost partition, for example.
- smartmontools contain utilities that can be used to inspect S.M.A.R.T. values of hard disks. By analyzing these numbers you may get a hint if your hard disk is starting to show signs of breaking down.
