If I do a fresh installation of ubuntu from an uninfected cd, will it remove all the existing rootkits/malwares/spywares/viruses etc if any ? Is formatting the hard disk required before reinstalling or these malicious programs will be removed even if the disk is not formatted before reinstalling?

You are required to format the disk completely. There are rumours and even proof of concepts of rootkits hiding in the BIOS, but I haven't seen them in the wild yet.

- Switching power off before booting from CD is not very time expensive! (And could maybe prevent warm-boot issues)F. Hauri - Give Up GitHub– F. Hauri - Give Up GitHub2014-03-10 17:05:37 +00:00Commented Mar 10, 2014 at 17:05
