I recently fired up Disk Utility to format a disk, and in the left sidebar, below the divider line, it's showing a disk image called "decryptedFile.dmg", which shows it contains (unmounted) a volume called Flash Player.
This file is located at /var/folders/zz/zyxvpxvq6csfxvn_n0000000000000/T/. I tried to navigate to this folder via "cd" in Terminal but got "permission denied". I was able to access /var/folders/zz/ and the folder named zyxvpxvq6csfxvn_n0000000000000 has both owner columns showing "nobody".
I'm wondering if this is leftover from a legitimate Flash Player install/update, or if I should be suspicious that this is some sort of hack or trojan or something. And then, what should I do about it? Just drag it out of Disk Utility, or do a sudo rm or something to get rid of it? Or do some more serious virus/spyware eradication.
