I have a portable harddrive (Western Digital) for my Mac. I plugged it into my buddies Windows computer to copy some movie files that I am editing for our film. When I replugged my computer back into my Mac I had these 3 files on it: autorun.inf haihaep.exe hailhaep.scr They are all locked and it won't let me unlock these files to delete them, any ideas?
Yea, it looks like your buddies computer was infected and infected your external HD. It won't effect for Mac at least, but will infect any Windows machine you connect it to. Deletion option: Open Terminal: sudo rm path to file Easy way to get the path in is the drag the file from Finder to the Terminal window. Just make sure you have a space after the rm. Do this for each file. The command will ask for your password the first time and you'll need to be an administrator.
