What are these mysterious documents on my hard drive?
I was out of town for the last 3 weeks, so no one was using my home computer, but I left it on anyway. I normally never turn it off, unless I'm rebooting it or moving it. Upon returning home, I woke it up and opened the Finder window, I found 3 mysterious 4kb documents on my hard drive. These were not in my Home folder, but were sitting above the Applications folder in Finder. They weren't there before I left town. All three of them were dated differently. One a month for Sept., Oct., and Nov. Very odd. When I try to open them, I get a message saying, " The document "" could not be opened. You don't have permission. To view or change permissions, select the item in the Finder and choose File>Get Info." So I did this and I got no useful information. I ran a Disk Permission - Repair Permissions and still could not open these documents. I decided to delete them.
Then today, I find there's another one, with the time stated as being Today, 1:36 AM. The others also had early morning hours attached to them too. So it appears to be the exact same sort of thing. What the heck are these documents and why are they suddenly appearing on a monthly basis?
