Answers to your questions:
1. They might work, but its probably not safe to download and burn anything to a disk without risking it getting infected and you using infected files to restore.
a1: If the error doesnt get fixed youll have a corrupted version of windows forever. In this case though with my expiriences, I just reccomend starting completely new.
a2: No, you can restore full functionality and be virus free with a clean format.
a3: Sorry to say this, but when you get a devastating worm like that, its almost stupid to save files from an infected machine and put them on a new machine. The virus has already had the chance to corrupt any files it was programmed to.
3. The worm prbably wasnt the cause of the error, the worm probably replaced many system files with its own virus oriented files and when norton removed them, your system was left with nothing to boot on.
Heres what course of action I think you should take.
Wait for your official windows xp cd to arrive in the mail. Until then, i reccommend shutting off your computer to avoid any possible problems.
When your xp cd arrives do the following:
(A printable version of my guide on how to reformat can be found here)http://www.techsomething.net/SupportMiscel...terFriendly.htm
1. Place the Windows XP CD into your CD drive. Reboot your computer with the CD in the drive. It depends on your system, but most of the time hit F12 to get to the boot menu.
2. You will be taken to the boot menu, once there, use your arrow keys and naviagte to the command that says boot from cd. After, Once the boot menu pops up hit boot from disk, Windows will take a few minutes scanning your files and a blue screen will popup and say loading windows files and all that stuff.
Once its finished there will be three options, one to repair windows, one to reinstall windows, and one to exit and go back to your regular computer operating stance. Hit the key that takes you to a clean windows install If your trying to remove a virus you need to completely reinstall windows, including delete the partitions.
3. You will be asked if you wish to create a new partition. First, select the partition that you already have, and press D to delete your existing partition, and then L to confirm that you wish to do this. This will completely erase all documents and programs (and viruses!) off of your computer.
4. You then need to create a new partition. To do, this select C.
5. When asked what size you wish to make your new partition, just press Enter to make your partition the maximum size.
6. Select the partition that you have created to install Windows XP on by pressing Enter.
7. Your computer will prompt you asking if you wish to do a quick installation or a regular installation. Either will work fine, but "quick" goes faster.
8. Now you need to select Format the partition by using the NTFS file system.
9. Windows XP will now be installed. This may take some time and then your computer will reboot. From now on all the screens during the installation process will look like the Windows XP screens you are used to.
10. Make sure you properly enter your product key. This is either on the CD that came with your version of Windows XP or on your computer's case.
11. Windows will now complete the installation. XP will likely detect the drivers for all of your hardware, but you may need to use the disks that came with your hardware to install some of your hardware. You will now also need to install any software you need. Most importantly, INSTALL ANTIVIRUS SOFTWARE, AND RUN WINDOWS UPDATE IMMEDIATELY TO PROTECT YOUR COMPUTER!!! If your connection has been disabled, you will not be able to run windows update. However, you can download the patches from http://v4.windowsupdate.microsoft.com/en/default.asp
Hope this guide helped you.
