I have MacUpdate installed (which I got with their Spring Bundle).
I noticed that it tries to check for updates every hour for some reason. The app itself is not running so it must be some agent or daemon.
Here's example log entry (with network off):
06/04/2011 22:33:00 MU App Search[1916] APP KEY 447266

I was looking for a setting that could determine the frequency (ideally switch it off completely) but didn't find anything.
Using Lingon I found one Agent that's suppose to run every day at 0:35 which would be fine, but as you can see from the log, it's seem to be run hourly.
Any ideas?
UPDATE
Did some testing and these are my findings...
After disabling the MacUpdate LaunchAgent it gets re-enabled by MacUpdate Destkop app every time it launches. Same happens if I delete it altogether.
