Here is my situation - PC running Windows XP Professional.

My friends sends me a link which eventually leads to it being a trojan horse that infects my computer. It completely takes over, disabling all my anti virus, not allowing me to run or install any type of anti virus, and even blocking websites that offer virus removal help (re-routing of IP). In an effort to fix my computer, I used the windows CD and tried to use the repair and recovery mode to reinstall windows. Now the computer just hangs and nothing can be done.

The good thing is that I can still access my harddrive as an external on another computer via sata usb cables. My question is whether there is a way for me to try and fix the boot and startup files on my computer so that I can salvage my computer and fix it the right way? Thanks so much and happy thanksgiving!

If you cannot boot up in Normal or Safe mode, you may be able to use a Windows XP bootable Floppy Disk to boot from a diskette instead of your hard drive. If your hard drive's boot sector or Windows' basic boot files have been corrupted, this disk will circumvent the problem and boot you into Windows. If you don't have an emergency boot floppy, you may be able to use one created on another PC running Windows XP but there's no guarantee that it will boot your machine.

"Resolving Boot Issues with a Boot Floppy Disk".
"How to obtain Windows XP Setup boot disks" and select the download that's appropriate for your Operating System. The Setup boot disks are available so that you can run the Setup program on computers that cannot use a bootable CD-ROM.

Another option is to create a Bootable CD:
Bootable CD FAQs
How To Boot your Computer from a Bootable CD or DVD
How to Create a Bootable Windows XP Setup Disk on a Preinstalled/Preloaded Windows System
Creating A Windows XP Recovery Console CD Image

However, the better course of action would be to reformat and reinstall the OS. Some types of malware can result in a system so badly damaged that a Repair Install may 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. Please read:

"When should I re-format? How should I reinstall?"
"Help: I Got Hacked. Now What Do I Do?"
"Where to draw the line? When to recommend a format and reinstall?"

http://www.bleepingcomputer.com/forums/ind...=182944&hl=

Since you were able to boot up and post a log, you can disregard my previous instructions.

After posting a log, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a HJT Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the member assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the HJT Team should be the only members that you take advice from, until they have verified your log as clean.

To avoid confusion, I am closing this topic until you are cleared by the HJT Team. If you still need assistance after your log has been reviewed and you have been cleared, please PM me or another moderator and we will re-open this topic.
