I am new to Mac and like it so far. However, I am having some difficulty in one area. Whenever I connect an external device such as a mp3 stick or my psp via usb the device will autorun like crazy either uploading or downloading something. I cannot tell. When I hook it up to my PC I will find hidden files like .fseventsd and .spotlight . And if i delete something on the device it will create a trash bin and just move it to the hidden trash bin IT WON'T DELETE IT. Is there malicious software on my OS causing this or is this a simple fix I can disable in the control panel? Thanks ahead.
