I used the Wizard to create on CD (not ISO) the NBRT.
Boots OK & Scans OK
A few questions if I may...
1) What accounts for the NBRT 200k less files scanned vs. NIS full scan.
2) What accounts for the NBRT slooower scan vs. NIS.
I understand the scan runs via my RAM. Is my RAM the only cause for the slooower scan or might other sys resources like front side bus speed be causal.
3) The NBRT ISO may used as a recovery CD or DVD on any computer.
Does any mean any computer or any computer with a Norton product. Does NBRT ISO serve as a recovery tool to a Windows environment or to a Norton environment - and will it update and scan any computer with or sans a Norton product.
4) The NBRT USB while easier to update. Might the NBRT USB scan faster as it also runs through my RAM.
I have read the Help files. Just don't fully understand em'.
There is a new NBRT out. I don't know which one you have and I have never used it. I can give you the link for the new one. There is a link on that page also. I think it says Learn more or more information or something like that. I've just found the link now for it. Perhaps looking at this may help you out.

Actually let me address the other questions first:
1. Double checking with Symantec.
2. The recovery environment runs as WINPE and the hardware profile is probably not identical to the full Windows environment.
3. NBRT is a recovery tool whose main purpose is to scan for malware after booting from non-infected media. It is not a Windows recovery environment. Technically NBRT is not supposed to be used on any computer which does not have a licensed version of Norton Software such as NIS.
4. It would not scan faster but it will boot faster if you connect a USB flash to a USB 2 port.

Thanks ...

Help files > Norton Bootable Recovery Tool is integrated with Windows Preinstallation Environment (WinPE).
OK, integrated with = runs as
3. NBRT is a recovery tool whose main purpose is to scan for malware after booting from non-infected media. It is not a Windows recovery environment. Technically NBRT is not supposed to be used on any computer which does not have a licensed version of Norton Software such as NIS.
Umm, Technically NBRT is not supposed [...]
Help files > You can create a Norton Bootable Recovery Tool ISO file on your computer. You can burn this ISO file to a CD or DVD and use it as a recovery CD or DVD on 'any' computer. You can also use this ISO file to point to 'any' virtual machine as a virtual CD-ROM.
Umm, so what might an ISO image facilitate for the user vs. non ISO.
4. It would not scan faster but it will boot faster if you connect a USB flash to a USB 2 port.
2. I'm not sure what distinction you are attempting to make here. NBRT runs on the WINPE environment just like NIS runs on the regular Windows environment.
3. The NBRT is not intended to be used on computers for which there is no licensed Norton product. Yes it can be used on any computer from a technical perspective. That does not mean that NBRT can be used "legally" on a thousand computers which don't even have licensed Norton products. Take a look at the note on the NBRT download page here. See also this post from a Symantec employee. NOTE that this post was written before the 2011 version of the NBRT was available so the link given for updating the NBRT with custom drivers no longer applies since that is now integerated with the NBRT itself.
2. I'm not sure what distinction you are attempting to make here. NBRT runs on the WINPE environment just like NIS runs on the regular Windows environment.
Not trying to make any distinction about anything. Just trying to confirm the meaning of the verbiage 'integrated with' ....
NBRT runs on the WinPE environment. Understood ! The verbiage 'integrated with' conjured up an alternate scenario. I get it... 'integrated with' mean 'runs on'.
3. The NBRT is not intended to be used on computers for which there is no licensed Norton product.
I freely stipulate that the NBRT as per Norton is not intended to be used on computers for which there is no licensed Norton product. I freely stipulate I will stay within the four corners of the law. Again, it's just a verbiage issue. The Help text re the ISO points to 'any' a number of times. I wanted to understand what it is about the ISO CD that differs from the non ISO CD. Why offer a non ISO and an ISO. Why use 'any' over and over. I imagined Norton was trying to tell me something. I imagined 'any' meant 'any'. All the NBRT media runs on the WinPE environment. What can a user do with an ISO CD that differs from the non ISO CD. Last year we were using GearISO Burn. This year we have a Wizard. Guess, I'll burn an ISO and see for myself.
Any luck with #1. What accounts for the 200k difference. NBRT 350k vs. NIS 550k
Have you run the new NBRT. Have you experienced fewer files scanned ? Maybe, I used a bad CD or have a corrupt NBRT. I do not recall if there was a similar file difference last year.
Hope this helps.
Yes, most assuredly all your posts always help.
Best wishes.

I am not trying to re-invent the wheel. Just trying to enhance my knowledge.
Symantec has skilled technical writers. I consider myself an average home user. I try to read and comprehend all that Norton Help text offers. Symantec invested resources providing the Help text. The least I can do is read them and if necessary ask for clarification. May not always be realistic...but, it is reasonable IMHO.
No I am still waiting on #1 and yes I also see a difference so please stay tuned to this channel for further weather information..... OK so I digress but yes I will definitely get back to you when I do hear something.
There really is no such a thing as an ISO and non ISO CD. An ISO image can do nothing by itself, it is only a file. You need an ISO aware application to burn this to CD (or flash) at which point it is no longer an ISO image, it becomes a bootable CD or flash and is seperated into it's individual files.
I could give you an ISO which when burned with an ISO aware application creates an exact duplicate of a boxed version of the NIS CD. The ISO itself is useless until you burn it with said application.

As always u r professional and courteous and most willing to go the extra mile.

Yes, thank you ...That's exactly what I've been trying to get my head around. Once I burn the ISO image I have a bootable CD. Just like last year with GearISO Burn. Symantec gave me two options to create a bootable CD.
Norton Bootable Recovery Tool CD or DVD >
Norton Bootable Recovery Tool is integrated with Windows Preinstallation Environment (WinPE). Therefore, you can run Norton Bootable Recovery Tool only from a CD, DVD, or USB key.
Norton Bootable Recovery Tool ISO file >
You can create a Norton Bootable Recovery Tool ISO file on your computer. You can burn this ISO file to a CD or DVD and use it 1) as a recovery CD or DVD on any computer. You can also 2) use this ISO file to point to any virtual machine as a virtual CD-ROM.
1 ) on 'any' computer - I imagined some expanded capability. & 2) ISO file to point to any virtual machine as a virtual CD-ROM - I have no clue about # 2 ~ A virtual machine (VM) is a software implementation of a machine (i.e. a computer) that executes instructions (not programs) like a physical machine. "Over my pay grade". A virtual machine was originally defined by Popek and Goldberg as "an efficient, isolated duplicate of a real machine". Current use includes virtual machines which have no direct correspondence to any real hardware. "Say what ! Way, way over my pay grade".
I could give you an ISO which when burned with an ISO aware application creates an exact duplicate of a boxed version of the NIS CD. The ISO itself is useless until you burn it with said application.
Yes, that's what I thought.
Hope this helps clarify.
Helps -- Yes, as always. May just be beyond my skill set. The master is great. The grasshopper is lacking.

to be continued...please stay tuned to this channel for further weather information.
Regarding number 1, I've heard back from Symantec. As has been posted in other threads, I have reconfirmed that NBRT does use the same scanning engine as NIS. However as explained by them, the difference is in the scope of the scanning. One example Symantec gave me is that in the NBRT the scanning of compressed files has a much smaller scope than with NIS. Bear in mind other threads which call out the fact that malware cannot run from compressed files, it is only when you access them that they can do harm. Since the goal of the NBRT is to catch "active" malware it should not be necessary to scan compressed files at all from an NBRT perspective.
Another difference is with certain known OS files such as .msi files which the NBRT also may not scan.
These things plus other subtle differences in the scope accounts for a significant difference in the number of files actually scanned in the NBRT environment.
In the end if you assume that a particular computer has a malware infection present and active, the NBRT will have a better chance of finding it than NIS, since it runs from a known non-infected media.
Hope this clarifies and for me also to explain the difference in file count.

Aha! ...same scanning engine as NIS but, difference in the scope of the scanning.

The weather is nice and sunny and relatively warm for Oct. here in my neck of the world.. Just to continue with a bit of a weather report since it was mentioned in the thread already. LOL.
