Got a problem in Hardy Heron Packagekit

Hello Experts,
After I had upgraded the Hard disk of my HP Mini 110 using again my favorite Hardy Heron were I installed some nice application in a source file. When installed new software from Packagekit version 0.1.6, can’t understand after I reboot laptop the notification displays in my screen. The notification appeared in the right down corner of screen. Any ideas about the notification appeared in my laptop? Thanks in advance in giving good inputs.
