I have a trogan on my computer in the system32 directory. I can not remove it because it is currently running. I cannot remove its register entry because it will automaticly put them back in there. Is their a way I can delete it from the system before it is loaded into memory. I have tried to use autoexec.bat to delete it but I don't think windows XP uses autoexec.bat anymore. A windows XP formated disk does not allow me access to the C:\. Any suggestions?

You could try using HijackThis to delete the registry entry. If that doesn't work, boot the PC using a Knoppix CD, mount your main HDD as read/write, and the use Knoppix file manager to delete the file.

Find out what trojan it is, then Google for a dedicated removal tool for it. Failing that, try booting in safe mode and deleting it, but most virus writers are smarter than that, the last one I got would survive safe mode. (it was Virtumonde IIRC)

The Knoppix thing is a good idea, but it might not work if your drive is NTFS. Last time I checked, Linux access to NTFS was read-only. As a last resort, maybe you could put the hard drive in an external USB caddy and use another computer to delete the virus.

You're right, Windows XP doesn't use autoexec.bat, because it doesn't run on top of DOS any more. DOS went out with Windows NT.

If you know DOS, you could use some format of DOS bootable media, and boot into DOS to remove it. It seems that you might know your way around DOS pretty well, too.

Knoppix is now able to mount NTFS volumes in read/write.

Also, if Knoppix fails to do this, I know for a fact that the Ubuntu live cd can.

It is Virtumonde, at least one of the PC scanning tool says. I do not have knoppix to use, if I can find my windows XP disk, I then would beable to boot and have access to the hard disk.

"If you know DOS, you could use some format of DOS bootable media, and boot into DOS to remove it. It seems that you might know your way around DOS pretty well, too."

I have tried this. It will not allow me to access the c:


UPDATE:

I got rid of the trogan. I found this autorun manager program that can delete the infected files before they are loaded.

Great to hear!

And another boot CD option is BartPE. It can boot a GUI of XP off a CD and access NTFS drives with ease. Networking is hard though mad

I know it's a little late, but I found this:

May be of interest to XP users, since SP3 just came out on automatic updates, and it delivers a new copy of winlogon.exe that may undo any, err, "activation procedures" you might have used. This is a great case of something that would be classed as a Winlogon virus if it wasn't planted by Microsoft themselves suprised
