Can't get rid of strange virus/spyware :-(

[Lars-Erik Østerud]

Clean a friends system, but there are something left I can't get rid
of. Both Ad-Aware and Spybit S&D finds it. It is in the "Startup"
list, but when they try to remove it it just reinstalls itself. Even
tried removing the entries in the registry. But they keep coming back.

Microsoft Anto Spyware and Malisious Software removal doesn't find it.
Neither does the anti-virus programs. But when installed it launches
IE with a window with commercials (stopped that by blocking "Winlogon"
in the firwall So somthing is very very wrong. But what do I do?

Details:

In "startup" (actuall it suncribes to "Lgon" and "logoff" events, but
it show as "system.ini" in Spybot S&D" under the "Startup items")
there are two DLLs that are launched:

"tdcyw.dll" always has the same name, the other DLL changes name (and
description) all the time: dnp0018me.dll, r0p8la7u1d.dll,
mv6ul9j91.dll are only some of the names..

Tried to delete those DLLs, but of course they are in use. But I can't
see any processes that should not be there...

I forgot to note the names on the spyware "Ad-Aware" found :-(
But it finds 12 entries each time (even after I delete them).

Thought I could boot to "command prompt only" but that is not in the
boot meny (it's XP home), the obly choice with "command prompt" boots
XP first (to GUI) then launches a "cmd" (and then the spyware has
allready reinstalled itself and run). Is there a way to get a "cmd"
windows without launching XP first with XP home (works on XP Pro)?

Boot into Safe Mode and run the scans there.

Frank Saunders, MS-MVP OE:

Boot into Safe Mode and run the scans there.

Tried that too. Same problem. Can't delete the files. And they
reinstall anyway. Also tried holding Ctrl-Alt-Shift at start (that
usually stops most autostarting programs from launching).

In windows control panel add/remove programs uninstall surfsidekick,
newnet or newdotnet and WebNexus if they are listed, restart the PC if
prompted.

Download and run Look2Me-Destroyer: http://www.atribune.org/content/view/28/
or
Symantec tool -

or

Good luck

Delete the dll extension. It always works for me.

Unregister the mentioned DLL files first.

At the command prompt, navigate to the directory where the DLL files reside.
Type "regsvr32 /u tdcyw.dll"
Type "regsvr32 /u <random DLL name>.dll"

Now delete the DLL files.
