Unable to Scan XP computer that won't boot with Norton Antivirus

Hi Folks,
I need to scan a WinXP home computer that doesn't boot at all with Norton Antivirus.  If I put the NAV2003 or NIS2004 disk it only scans the A drive (CDROM).  I tried to goto the dos prompt and look at the HD however it doesn't recognize it when booting from the NAV disk.  Now I made an awsome Barts PE boot disk and I can see the HD fine, copy files to my network share etc.  

Symantec states that you can run NAVDX  c: /l /doallfiles /prompt /cfg:c:\vdefs  where vdefs has the latest definitions.  

This is the string I want to run.  So I tried to copy NAVDX.EXE from the CDROM to the bad HD and run from there w/ Barts PE DOS Prompt however I receive the error "NAVDX.EXE is not a valid Win32 Application".

I have a network share to my server however I don't really have internet access so I can't do scan from the website.  

Any ideas would be greatly appreciated.

cheers,
dwcorwith

Hi dwcorwith,

Your solution od using Barts is very ingenious. The reason why you get that message when trying to run NAVDX.EXE is that NAVDX is a DOS-based module of NAV, useful when a user is having trouble booting Windows. It seems like Barts will only recognize legit Win32 apps. What you could try is running NAVW32.EXE directly from the Norton CD, but that won't let you use the latest definitions file. The other option would be to install and update NAV in a second machine, then remove and set the problem HD as a secondary/slave and scan it there using the Barts CD for booting.

Good Vibes!

Hi Lobo,
Thanks, I will try the NAVW32.exe.  I thought if you booted to a Norton CD it was suppose to be able to scan the HD?

Hi dwcorwith,

You boot the machine and scan from the Norton CD, but it will use the outdated definitions file in the CD.

Let me know how the NAVW32 scan go.

Good Vibes!

Hi Lobo,
I tried to run navw32.exe from the Bart's PE prompt to no avail.  Also it is not an executable file available if you boot from the NIS2004 cd.  It want's to run NAVDX in a W98 environment and that is why it can't see the ntfs drive.  So this may be a question for Symantec, how do you check an ntfs drive w/ a Norton Antivirus cdrom?

Hi Dwcorwith,

That's very interesting, that Norton assumes everyone uses Win98.

In such situation what I would do is to plug the hard drive into another machine with W2K (NTFS) or XP and scan it there. As an added precaution, I'd plug it as a secondary master with no slave; the reason being that the drive is isolated that way.

Another option. How about booting with a XP Boot Floppy and running Norton directly from the CD?

Good Viibes!

Hi Lobo:
Well, I rebuild several computers a week for customers and wanted to get away from having to pull HDs each time it happens.  Barts PE is just what you recommended, a boot CD for NTFS.  It's one of the only programs out there that will boot to NTFS.  I've done what you recommend in the past and it works fine.  I like the idea of configuring it as another master, good thinking.  

What I'm really looking for is a Bart PE (http://www.nu2.nu/pebuilder) that will also do the virus scan either from the same boot cd or from the corrupted HD.  This would be a great tool for a technician who rebuilds computers on a regular basis.  As you said in a previous thread, NAVW32.exe is for ntfs, you are correct.  I was able to run it from a good computer, from the command prompt but not from a computer booted w/ Barts PE.  So I think the solution has to do w/ the way Barts PE builder boots the CD.  Its suppose to be a full windows environment.  It sure looks like it.
Thanks

Hi Dcorwith,

I hear what you're saying. Although I am not a computer technician I am savvy enough to have become the "de facto" computer guy for my relatives and friends and I see the advantages of having such a boot CD.

Only a couple days ago, while servicing a machine, I uinplugged its old HD and plugged it into my main machine as a primary slave. Big mistake. I should have plugged it as a secondary drive, but at the moment it was easier to just plug it in the available IDE cable slot. After having my tools report the HD as "bad" I removed it and then my machine wouldn't boot at all; which has ended up in me having to install a new main HD and reinstall nearly 4 dozen programs. Yeah, it sux. That's the reason I reccommended that the problem HD be plugged as a secondary master, to prevent it from screwing up the primary master in case there's some physical damage in it.

One thing comes to mind. I read last year that Lindows was releasing a portable version of its OS (LindowsCD) which can be booted and run from a CD without need for an installation at all. I wonder if that would be the solution.

Hi LucF & dwcorwith,

Maybe a PAQ with refund?  The info about BART is a good reason.

Good Vibes!
