I have always desired to use knoppix as some operative system avoiding all kind of malware. I even thought to buy zeusgard usb pendrive but after some questions I found it was not what I was looking for. My question is: if I am only using knoppix 7.2 (cd) and it's not offering some port opened to internet, and browsing without javascript, is there any possibility to be hacked?. Even if the programs are outdated, as I am not accepting scripts from the internet and knoppix cd is read-only, I think I am secure. I thought about being hacked while all the programs are working in ram memory, but if I don't accept scripts from outside... what do you think?. Thanks.
