To make a long story short, I had a significant online financial account hacked and the funds stolen. In my estimation there are three areas in which the hacker could have stolen my info. My mac, iphone, or through the online site itself. In any event, I would like to clean up my mac just in case. I have a 13" macbook pro running the latest version of OSX. It originally came with Snow Leopard and the install disks. Do I need to use these disks or can I use command R while rebooting and start with the most current version of OSX? Also, any suggestions on transferring important files from time machine to the fresh system? I want to make sure I only keep safe files. I'm aware that the mac ecosystem is safe and that it is more likely that the hack occurred somewhere else but I've lost my peace of mind. Thanks guys.
