icons changed

i was fooling around with my security settings (like internet firewall) and such, then later i noticed that some folders in my user folder (documents) had a different icon--- the hazard one, i think thats the "folder to be burned" folder icon...




how can i change this?


also some of the .doc files, their icons are a gray ball, then when i click on it (single), i get a pic of the adium icon and the bluetooth icon... ive attached some pics

First thing, relaunch Finder. Go to the "Force Quit" menu and click the Relaunch button after you highlight Finder.
If that doesn't do it, then reboot.
If that doesn't do it, then use OnyX (or similar app) to clear your system caches.
