I have problems with the IMMUNISATION too. I get the message: "Diese Aktion wird aufgrund fehlender AdministationsRechte unter Umständen nur teilweise durchgeführt. Etc. etc. . . " This warning is correct, SPYBOT does a partly immunisation.
The warning "Windows Vista - Für einige Funktionen werden Administratorrechte benötigt" does not help. I am working under/with the administration-rights, but get only "partly immunisation". The current help does not help too much either. I am missing the option under SPYBOT to get the administration-right.
I hope it will work under the new release. 19.01.2008 http://forums.spybot.info/images/smilies/sad.gif
