I have a DoD CentOS install on a CD, so even if the code in RAM is infected, a reboot eliminates the malware. But I am not a UNIX guy and would prefer to work with Windows.
I had an old vs of Windows on a CD that did the trick (but lost it). Is there a variant of Windows that I could install and then make read-only? I assume the swap file would need to be on a read-write drive.
