O4 - HKLM\..\Run: [RunDLL] rundll32.exe "C:\WINDOWS\SYSTEM\BRIDGE.DLL",Load
There's your answer right there. bridge.dll is a component of the Gold Casino spyware/malware program, and that registry entry needs to go.
If you've got Gold Casino on your system, you've probably got other nasty unwanted guests on there as well. First- download, install, and run these two (free and excellent) adware/spyware removal tools:
SpyBot Search & Destroy: http://www.safer-networking.org/
Ad Aware: http://www.lavasoftusa.com
If they don't fix the problem, choose "run" under your Start menu and type "regedit" (omit the quotes) in the resulting dialog box; this will open the registry editor.
In the registry editor, navigate to HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Run. Right-click on the entry with the bridge.dll reference and choose "delete".
