Yes, you can burn anything you like to a CD. And you can copy it from the CD to the hard disk later. You could use a USB-stick, an external hard disk or webstorage (Dropbox, Skydrive) just as well.
But if it contains a virus before you burn it, it will still contain that virus after you copied it back. So you scan it carefully.
I have a problem with a virus on my desktop computer and although I have removed it a number of times using RKILL and then malware bytes and super anti spyware I am still having problems. I have decided to use my backup using Acronis which I did two years ago.
My question is can I remove some of the documents, pictures etc., onto a CD and will they be clean if I do that????
