In trying to create a custom SRD image, in which I have mounted the template/source ISO to a virtual CD/DVD drive, and I am creating the custom ISO to the Desktop--largely because doing this with external physical HDD and CD/DVD drives is not working either (that is, it is doing the same thing), the Create Custom Symantec Recovery Disk CD operation is not completing. It takes FOREVER to prepare the image and Save Session, then it goes to the Writing Session phase and the dialog window stays up the FOR HOURS AND HOURS.
Viruses? Malware? I use Norton AV 2011, which is updated constantly since the machine is always online during a login. In addition, I scan with Malwarebytes and Sophos Anti-rootkit now and then, for extra measure. I did full scans just now, and there is nothing out of the ordinary. No case can be made for malware/viruses, I think.
