I don't have dropbox installed, but whilst checking log files I've found that there is a /data/system/dropbox directory with log files from the 18th (which I think is the last time I rebooted my phone).

Does anyone know why this might be present? Is it possibly symptomatic of some kind of malware?

Titanium backup trying to put something in your dropbox maybe? – Dunhamzzz Dec 21 '11 at 17:20
"Dropbox" is a generic term and might not have anything to do with the file synchronization service. – Al E. Dec 21 '11 at 18:10
@Dunhamzzz: I don't have a dropbox account at all. – Logos Dec 21 '11 at 19:55
@AlEverett: I've never heard of dropbox being present in the context of a *nix file system. Do you have any examples? – Logos Dec 21 '11 at 19:58
@Logos titanium backup doesn't know if you have a dropbox account or not, it may still try to save files there – Dunhamzzz Dec 21 '11 at 23:32

/data/system/dropbox is not part of "DropBox" it is part of the Android OS DropBoxManager (not related at all to "DropBox").

This puts data from application crashes and kernel logs and such in this log directory. I know the market uses this directory(See #4) as well, probably to report application crashes.

You could probably remove the data in this directory, but DO NOT delete the directory and you may see logcat errors from parts of the OS/Apps looking for specific files in this directory.

edit: I deleted everything from this folder and rebooted my device afterwards, I had no issues with any applications, and it actually freed up some space on the device.

I've been using a recurring action with an app named macrodroid(kinda like tasker) to delete everything in that directory every few minutes or so while screen on and every hour while screen off. It seems to be more efficient than denying write permission to that folder (errors) I know this thread is old but thought I'd share since I'm not really cool with apps (and google) constantly uploading stuff in the background even after opting out of "make android better"
