i'm not a virus expert so don't take what i say as gospel. I've studied some viruss', and keep up on the latest news /dislaimer
It could be possible if the virus was specifically targetted or contained in any of the files burnt to the cd, IE, .exes, word files, .zip, etc. It simply would not be a viable distribution method of spreading via CD's(it was during the existence of the sneaker net), so very few viruses possess the capability of subverting a process of CD burning(btw, most OS's will prevent access of any sort to the cd/dvd drive during burning, so it would be pretty damn hard to infect a boot CD unless it was in one of the files being burned)


but to be sure:
boot to safe mode
ensure that the hash of the iso you're burning(i'm assuming its an iso) matches the hash from the web. Then burn the CD. Then scan the cd on a different computer.

I hope this is all correct, and I hope it helps you!
