Strange Windows problem

[Trones]

Hi.

I have a strange problem, i have tried find any answer at Microsofts KB and tried to Google, but still no clue. So i tought i try som forums and see if someone knows.

I scaned a computer for adware, viruses and crap like that, i cleared the adware stuff. But when i was about to scan for viruses i discovered that Norton had not updated for a while, after a while i manged to download the new patterns and ran a check. I found 10 files infected that Norton could not deinfect, delete or put in quarantin. Oh well i tought, i know the names of the files i need to delete, so rebooted the comp and went into safe mode. I can´t remember the virus name, but i hade 3 processes running, c:\windows\iexplore.exe, c:\windows\rundll32.exe and c:\windows\explore.exe. I tought i´d delete them and then run another scan.

But this is where my problem appears. I can´t logon to the system anymore, there are 4 local users plus administrator. All users, includning administrator starts the login sequense and then after about 2 - 3 sec "Saving settings" and then "Log out".

It dosen´t matter if i'm in safe mode or normal mode or any other mode.

I tried running a recovery console and delete the files, i copied them to a separate folder first in case. Still the same problem.

Its a Windows XP Pro SP2.

Anyone here have a clue?

To restore a clean version of Rundll32.exe:

1. Mount the Windows XP CD-ROM.

2. Open a CMD.exe session.

3. Type expand <CD-ROM:>\i386\rundll32.ex_ %Systemroot%\rundll32.exe and press Enter.

4. Shutdown and restart Windows XP.

This should work for this file but i do not know about the other two.
