unable to remove problems detected

[Chyrise]

Hi! I'm new to all of this & need some help. Just installed Spybot, scanned my computer & was able to remove some problems detected, however it's telling me that some of the problems detected could not be removed because I am not the administrator. I checked and yes I am logged in as administrator (no one else uses this computer). I'm sure this has a simple solution- I just don't know it. Could some of you more computer literate people help me???
