I just started noticing this menacing and unknown icon in my menu bar. It's a red exclamation mark in a blue circle with a green arrow. Here's an image:


If I click it, whether I press Cmd or not while clicking, nothing happens. Any ideas?

I had no luck with Google Reverse Image Search. It's too small for Tineye... Here's the cropped image I used: ... The icon suggests that it could be network/download related. Hmm. – iglvzx May 31 '12 at 7:31
Do you remember installing anything? Does it happen for other users as well? Anything in your Login Items in your user account options? – slhck May 31 '12 at 9:06

I had the same problem and found out that the application displaying the icon is Mobile Partner. It is trying to communicate that there is and update for the device. After multiple reboots I was able to click it and get the update process started.

Have a look in Activity Monitor for any strange apps. Also try right clicking on it. slhck's advice (looking at the login items in the user accounts pref pane) is also good.
