Probieren wir die Löschung, manuell, dürfte für Dich am einfachsten so sein:

1.) Lade Dir von hier Avenger:
Swandog46's Public Anti-Malware Tools (Download, linksseitig)

2.) Entpack das zip-Archiv, führe die Datei "avenger.exe" aus (unter Vista per Rechtsklick => als Administrator ausführen). Die Haken unten wie abgebildet setzen:



3.) Kopiere Dir exakt die Zeilen aus dem folgenden Code-Feld:

registry keys to delete:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{055FD26D-3A88-4e15-963D-DC8493744B1D}
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{5C255C8A-E604-49b4-9D64-90988571CECB}
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{AA58ED58-01DD-4d91-8333-CF10577473F7}
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{AF69DE43-7D58-4638-B6FA-CE66B5AD205D}
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects\{EEE6C35C-6118-11DC-9C72-001320C79847}

registry values to delete:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Toolbar | {855F3B16-6D32-4fe6-8A56-BBB695989046}
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Toolbar | {2318C2B1-4965-11d4-9B18-009027A5CD4F}
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Toolbar | {EEE6C35B-6118-11DC-9C72-001320C79847}

files to delete:
c:\programme\google\googletoolbar1.dll

folders to delete:
C:\PROGRA~1\ICQTOO~1
C:\Programme\Google\GoogleToolbarNotifier
C:\Programme\SweetIM
         

4.) Geh in "The Avenger" nun oben auf "Load Script", dort auf "Paste from Clipboard".

5.) Der Code-Text hier aus meinem Beitrag müsste nun unter "Input Script here" in "The Avenger" zu sehen sein.

6.) Falls dem so ist, klick unten rechts auf "Execute". Bestätige die nächste Abfrage mit "Ja", die Frage zu "Reboot now" (Neustart des Systems) ebenso.

7.) Nach dem Neustart erhältst Du ein LogFile von Avenger eingeblendet. Kopiere dessen Inhalt und poste ihn hier.

8.) Restliche bzw. verwaiste Einträge mit dem CCleaner aufräumen

Habe das mit dem Avenger gemacht. Hier der Logfile:
