I tried symantic, stinger and trend to remove it. Norton 2003 also did not remove it "O20 - AppInit_DLLs: C:\WINDOWS\System32\kbdhinc.dll" keeps coming back and Norton 3003 detects it, but unable to remove it. I can't seem to ring it in the reg.
Any suggestions? Thanks

Mosaic1 has created a bat file that should help us, download it from here.
http://www.geekstogo...=download&id=34

A few setup items first we need to do, make sure you can view all hidden files and folders, use this link for help.
http://www.xtra.co.n...1916458,00.html

Next, review this article How to take ownership of a file or folder in Windows XP

Sign Off the Internet and Stay Off Until All Steps Are Finished

Extract the batch file (hiving.bat) and run it. If you have script blocking enabled you will get a warning. Please allow this to run. The script is just producing a message box. Double click on the batch to run it. After a reboot the super hidden nasty file will no longer be loaded and will be visible.

Restart into Safe mode and find this file:
C:\WINDOWS\System32\kbdhinc.dll

Right click on the file and choose properties.
Use the security tab on .dll and take ownership.
Change the 'everyone special' to
'you> with Admin rights-> FULL control
Then try to delete it, if that fails try to rename
it first to different name+ext.
Example:
ctl.dll>bleh.txt
bleh.txt > badfile.111

Once you have successfully deleted the file restart into Regular Windows mode.

Run CWShredder immediately. Press the 'Fix' button to clean.

Run Ad-aware
Restart.

Report back if you're successful or not.

The manual removal steps for the backdoor.agent.b from NAI seemed to do the trick. I will also try the suggestions you listed. Thanks again

I was looking at the pc for a friend's teenager, so I can't get a new log, darn. It could have been the Download Ware had those keys left in the registry.

Thanks again for all the Help, this is a great Forum !
