Spyware in RUNDLL32.DLL

January 22, 2005 at 13:02:24
Specs: Win 2k, 300 MHZ/256 RAM

Im having trouble with some things, and ad-aware cant take car of it even in safe mode. Surprisingly this thing runs in safemode also.

When RunDll32.dll is running i get pop-ups = when i get rid of it pop-ups stop. Ad-Aware notices this issue but it cannot remove it because files are in use...

What could I do?

Thanks in Advance

The sircam worm will do what you say ,,, If you can ,, You might try copying a new clean copy Also found this... not sure if it's related Sounds funny ,nonetheless

When executed, Funner will copy itself to the WINDOWS directory under the name rundll32.dll and alter registry entries to ensure the worm is started. It will also copy itself under WINDOWS SYSTEM directory as


The following registry keys are altered to ensure the worm runs upon next reboot

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run "MMSystem"
"c:\winnt\rundll32.exe "c:\winnt\system32\mmsystem.dll"", RunDll32"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run "MMSystem"
"c:\winnt\rundll32.exe "c:\winnt\system32\mmsystem.dll"", RunDll32"
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon "Userinit"

Funner also overwrites the local hosts file with a file containing various URLs.

NOTE! There is Windows system DLL named rundll32.dll under WINDOWS SYSTEM directory. This DLL is part of Microsoft Windows operating system.

MSI 845e mb 768 mb ram and a p4 2.4n running xp ,win 2000 advanced server and win 98 SE alot to learn and I know so little !!!!

Have you tried Spybot SD?

If Spybot can't get rid of it because it's in use, it will ask you if it can run at startup before the offending file loads into memory.
