Du mußt unter "Free Removal Tools" auf der linken Seite auf "Rescue CD" gehen und dann recht unten dem Downloadlink zur .zip-Datei folgen. Da gibt es auch einen Users Guide.
EDIT: hoffe Du kannst etwas englisch, wenn nicht sag Bescheid...

Using the Rescue CD
1. Place the F-Secure CD in your CD drive and switch the computer on. After a
few seconds you should see a prompt that shows F-Secure Rescue CD.
2. Press ENTER within 15 seconds after you see the prompt to start Rescue
CD.
3. Use the arrow keys to select Next and press ENTER.
4. Wait for the latest virus definition database to be downloaded from
F-Secure. This is finished when you see the End User License Agreement
window.
5. Press PAGEDOWN to read the agreement and then select Next and press
ENTER.
6. Select I Agree and press ENTER if you agree to the terms.
7. Select which drives you want to scan.
8. Select Proceed to scan and press ENTER.
9. When the scan is finished, press ENTER to see the scan report.
10. If any malware were found, you can see which files were renamed by the
Rescue CD. Select Next and press ENTER when you are ready to continue.
11. Select Restart and press ENTER.
12. Wait for 5 seconds for the computer to switch off. The computer restarts.
13. If you see the same screen as you did in step 1, wait for 15 seconds for the
computer to start normally.
If you do not see the F-Secure Rescue CD screen you should check
that the computer can start from CD. To do so:
1. Restart the computer.
2. Hold the BIOS options key while the computer starts, usually this
is one of F1, F2, F10, F12 or DELETE. If none of these work,
consult the documentation for the computer.
3. Change the option that determines which device the BIOS tries
to find the operating system from, so that the CD drive is
searched first.
4. Save settings and restart the computer.
The Master Boot Record is a small section at the start of a disk that
can be used to hide malware. You should scan the Master Boot
Records.
