can a virus be transfered to a cd or dvd?

My friend believes that cd's/dvd's are impervious to viruses, trojans, malware and/or stuff of that nature...

Depends

Depends on if the CD/DVD is writable/burnable. If it's a burnable disc, and you have some kind of self-replicating malware of any sort, it's entirely possible for it to transfer itself onto the disc along with other files.

If we're talking a commercially pressed music CD or movie DVD, then your friend is correct. The discs are read-only, so it would be impossible for any malware to get on them after they were pressed at the factory.

Long story short, so long as ANY medium is writable, you can have malware hitch a ride. Floppy disk, portable HDD, CD, DVD, flash drive, backup tapes, and anything else I may be forgetting off the top of my head. If you can write to it, then malware can infest it, simple as that.

Another way it can happen

If you have a software application installer file that is already infected, and you burn that file to a CD/DVD, then the infection will be included in the data.

Interestingly the first PC virus was written to a floppy disc and was never meant tobe such as evidenced by the fact that the authors included their names, address and phone number. FSecure recently released a video celebrating the 25th anniversary.

I don't think CDS/DVS can be affected by virus.
