That should be enough but I suggest you download your NIS from below since you will then get the most uptodate version:
New NIS 2011: This link is to the USA/CAN version; if you need a different version please say so.
Click on this link -- NIS 2011 This will download a single file of around 90MB which you should save on your hard drive where you can use it again if necessary -- Do not select Run but use Save when asked and remember where you put it!
With WIndows 7 I suggest you right mouse click on the downloaded exe file and select Run as Administrtor since I find it tends to give better results and use it with files I know are trustworthy.
Did your new PC come with any security software pre-installed say as a trial? If so you need to remove it and run a special clean up tool which we can give you directions to download from the related application website. Even if it's Norton it may be a good idea to clean up although if what you have as a trial is the same version as your defunct copy then all you need to do is click on Renew or Subscribe and enter the KEY .....
Let us know about this before you try to install Norton ....
GHOST is dealt with in the Other Norton Products Forum here in the Norton Community so I'd ask about it there.
