trojan has removed ....

Hi I have downloaded all programs in the (do this first) sticky but have a question But first (computer is a Dell 1 gig ram, pentum 4 processor about 2 years old and was running norton av (but this got in anyway?)

On my friends computer we cant accsess - windows explorer, or control panel
or add and remove. Also when trying to install some programs it says i dont have administrator rights. I can get around by going to run and hitting browse
it lets me in to see the files on the drives (i have deleated some Known spyware that way and used C Cleaner to remove registry items after reboot in to safe mode. (by the way even safe mode dosnt act correctly)
Also it keeps saying missing(C:\Windows\system32\rundll32.exe)
I am taking my windows XP cd with me in hopes of a repair install after I run the do this first programs from your sticky above. Any ideas or just wait till i can do reports if i can get that far?(I cant get to the internet but some thing is trying to as when i un plugged the DSL modem from computer i keep getting pop ups asking to work off line)
Any ideas or help apreciated
Herb

 

well I can't seem to get in to anything!! get a pop up stating that I dont have admin privlages (i am logged in as the admin) but I cant get to user
accounts to check if it has been changed? says rundll32.exe not found
(i was able to get to the windows folder and rundll32.exe is there)
this is frustrating
I cant even install the programs from the above sticky:cry
Any Ideas??
any help please
Herb

 

Ok I will try sunday when I go over there I'll let you know
thank you

 

no joy combofix wont run MGTools wont run eather This looks more and more like a nuke and pave job is the only answer!
Every program i try to run looks like it is loading(displays hour glass) but it just stops. and other times it says rundll32.exe missing, Or that i dont have administrater privlages.:***

 

Sorry yes it is in C:\windows\system32 folder.
It is windows XP home with service pack 2,
A good friend was able to pull critical files off the hard drive to a thumb drive
so now I am just going to wipe the drive and reinstall, Thank you for all suggestions,
Oh one more question - The system restore is on same drive in (fat 32 ) it should be safe to use this right??

 

I may be saying it wrong?
I am going to re format c drive and reinstall, But from the factory installed
hidden fat 32 System restore. It is used to replace the normal restore CD's(it is supposed to bring it back to like it was when first bought.)
If that is a bad Idea then I guess he will have to get a new coppy of XP and
go from there.

 

Well It is done and all seems well now just re installing all the extra programs and (hopeing he has saved all the Keys)
but thank you for all help.
