what is spin dump

i have iMac desktop and i am having a problem with running yahoo. other web sights seem to be ok just loading slow or not the whole thing. I go under activity monitor-Network and it says com.apple.geod not responsive. com.apple.geod and Flash Player (safari internet plug-in 3069) are in red highlight. is spin dump the same as cleaning up your hard drive for windows. I do not have Airport anymore and want to delete it from my comp. how can i do this.
