Ok so i have a 2011 mbp. Today i noticed the 'date modified' for some applications being before 2011. UnRarX was modified in 2006 for example. Also the programs Image Capture and Font Book are there (created in 2009) but i didn't install them and don't remember them being there before. So i think this must have happened as a result of 1)me authorizing an install from a program that included something malicious 2)someone booting into single user mode to f* with me or 3?)like some hackers somehow. is it likely caused by malicious code? do image capture and font book come with snow leopard?
