I had another posting in the Windows 7 forum that several users were kind enough to provide assistance on.  That thread ended with the recommendation to start this new topic.  I have read through the recommended preparation instructions for installing a firewall, running DDS logs etc.  My problem is that these steps all seem to assume that I can actually boot into Windows, which I cannot.  A little more history....Norton identified multiple attempted Viknuk attacks last week.  The standard Norton Security Suite scan was not able to remove it so I ran the Norton Power Eraser.  Power Eraser rebooted my machine and it hasn't been able to load windows since.  Windows Repair utility was not able to fix it.  Last night I ran Norton Bootable Recovery Tool, which identified Viknuk and reported that it had cleaned it.  PC still wouldn't boot to Windows.  I ran NBRT again and it said that it had made a repair to my registry.  Still wouldn't boot.  I ran Windows Repair again, which said that it had found an issue and would repair it.  Still wouldn't boot.  That's essentially where I am now.  PC goes through the posting process, displays Windows splash screen, proceeds to show the curser in the middle of a blank screen and after a couple of minutes shuts down and starts over.  Is it possible to run the DDS logs and\or whatever else I need to do from the command prompt or a boot disk since I can't get to Windows?  It's been a long time since I worked with DOS commands so I'm a little rusty at the CMD prompt.  The other option that I am considering, if it will work, is to simply start over with a new Windows install if that's easier at this point.  Sorry for the long explanation and thanks in advance for any help.

I forgot to mention, I also tried the "boot to last known good" option in the boot menu.  After letting it sit for more than an hour with no apparent action, I turned it off.

I decided to order a new laptop today.  The Viknuk'd machine was pretty old anyway so, although I will still try to get it back up and running, I'm not so concerned about repairing the existing Windows installation at this point.  I think my main concerns for now are:

 

1) Transferring the virus to the new machine.  Norton claimed to have cleaned it but if I transfer my data to the laptop am I likely to transfer the problem with it?  My plan is to reload Windows, connect it to my network and transfer my data files through the network. Alternatively, I can pull the hard drive and connect via SATA-USB conversion cable but I don't see this making a difference from a virus perspective. Bad idea or do I need to completely repair & clean the PC 1st?

2) If I reload Windows on the old machine, will it work?  Or has the virus damaged something that still needs to be fixed?

 

Thanks.
