Use a USB Flashdrive or Online Storage.
Insert Antivirus DVD in the DVD Rom drive
Connect USB flashdrive to the USB port of the computer.
Copy/paste (right click mouse) files from your DVD Rom drive to your USB Flashdrive.
Once the process is complete remove USB Flashdrive.
Second computer (netbook)
Connect USB Flashdrive to the usb port of the netbook.
I would recommend copying the files from the USB to the desktop and running/installing from there.
Online Storage instructions:
Go to: www.badongo.com make a free account.
Copy Antivirus DVD files to your desktop
then upload them online to: www.badongo.com.
Connect Netbook to the internet and download the same files from there.
Hope this helps.
