So today I've come home, wake computer up (iMac in sig, 10.8.3) and it has a finder window open Path: HDD>private>var>tmp> In this folder a compressed file is highlighted as follows: sysdiagnose_2013.05.212_08-16-32-CST.tar.gz Date last modified is today at 8:17am. I left this morning at about 8am. Also in this folder is a "com.wd.wddmservice" and "launchd" folder which have the same modified date/time of the 14th. Is this something I should be worried about? It really confused me as it just looks like someone has been on my computer and left this open and file highlighted. Its just very odd.
