im on fall break and back at home to do absolutely nothing... luckily, i have planetside on my parents computer, so i thought i'd jump on and pass the time. however, im not only having problems just starting the launchpad, but things in general are a bit sketchy.
first off, both my parents profiles are allegedly fine -- no problems reported with anything. however, on my account, i am unable to change a lot of appearance settings.

there is a lovely picture of my desktop. as you can see, i was able to change the color of the taskbar, but i cannot change the background image/color, the setup and location of the icons, or any mouse appearance settings.
as if thats not sketchy enough, when i try to run launchpad, i get the following message every time:

i am a computer administrator, so its not an issue with system rights. they have norton installed with a current subscription that is updated with the most recent definitions. its a very new computer that worked fine the last time i was on it (a couple months ago), so im not quite sure whats going on now.
anyone know what might be wrong and how to fix this? it seems awfully virusy, but it seems to only be affecting my profile (granted, i dont think my parents mess around with their appearance settings much, if any at all).
