If your computer no longer starts due to malware corrupting the operating system, or you suspect the security software has been compromised, you can use the F-Secure Rescue CD to securely boot up the computer and check the programs installed.The Rescue CD can also be used for more advanced repair and data recovery operations.

The Rescue CD contains Knoppix (a derivative of Linux), an operating system that runs completely from the CD and allows access to your computer's Windows operating system and hard disks.

Note: the Rescue CD cannot scan encrypted disks.

You can also download the Rescue CD updates to a USB drive (minimum 256 MB of free space) using a healthy computer with Internet access. You can use this USB drive to fix a computer that cannot connect to the Internet. Instructions on how to do this are included in the Rescue CD UserÂ’s Guide.
