You can try doing a Repair Install
from the Windows Recovery Console
. If you have a Microsoft Windows CD-ROM, you can get to the Recovery Console by booting from that CD and pressing any key when you told to 'Press any key to boot from CD
'. When the 'Welcome to Setup
' screen appears, choose the option, "To repair the Windows XP installation using recovery console", by pressing R
.Note: In order to use your Windows CD, the boot order must be set to start from the CD-ROM drive. If the CD is not first in the boot order, the computer will attempt to start normally by booting from the hard drive. The boot order is a setting found in the computer’s BIOS which runs when it is first powered on. This setting controls the order that the BIOS uses to look for a boot device from which to load the operating system. The default will normally be A:, C:, CD-ROM. Different computers have different ways to enter the BIOS. If you're not sure how to do this, refer to:
If you don't have your XP CD, you can download an ISO
of the Recovery Console files from one of these links:
Unzip the file and burn it as an image to a CD disk with MagicISO
or similar program to get a bootable CD which will startup the Recovery Console for troubleshooting and repair. This is especially useful for those with OEM systems with factory restore partitions or disks but no original installation CD. If you are not sure how to burn an image, please refer to How to write a CD/DVD image or ISO
and How can I burn ISO files to CD or DVD?
If doing a reinsatall using an original XP CD, you should not lose all your data. However, you may lose data that is stored in the All Users folder and default program templates and settings that are stored in the Default User folder after you reinstall, repair, or upgrade Windows XP. See You May Lose Data or Program Settings After Reinstalling, Repairing, or Upgrading Windows XP
: If this is a virus/Trojan related issue, you should know that some types of malware can result in a system so badly damaged that a Repair Install will NOT help!
. Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards. Starting over by wiping your drive, reformatting, and performing a clean install of the OS removes everything and is the safest action

Backdoors and What They Mean to You
Whenever a system has been compromised by a backdoor payload, it is impossible to know if or how much the backdoor has been used to affect your system...There are only a few ways to return a compromised system to a confident security configuration. These include:
• Reimaging the system
• Restoring the entire system using a full system backup from before the backdoor infection
• Reformatting and reinstalling the system
This is what Jesper M. Johansson at Microsoft TechNet has to say: Help: I Got Hacked. Now What Do I Do?
The only way to clean a compromised system is to flatten and rebuild. That’s right. If you have a system that has been completely compromised, the only thing you can do is to flatten the system (reformat the system disk) and rebuild it from scratch (reinstall Windows and your applications).
