I installed DbVisualize in Ubuntu 12.04. Now I don't want to use it anymore, so I deleted the folder "DBVisualizer" in my Home folder. Problem is I can still see the icon in the Dash.

How could I remove it completely from my system (for other apps too)?

uninstalling software usually cannot be done by deleting a folder. it depends how u installed it. so plz specify how the install has been done then can someone help you – Ashu May 17 '12 at 13:48
    
I run a "sh" file to install the software. So I thought I could uninstall it by deleting the folder. – quangtruong1985 May 21 '12 at 23:16
    
there would also be an uninstall.sh (most prob there is one) in the same folder. – Ashu May 22 '12 at 13:37

Dash picks up its entries from .desktop files placed in /usr/share/applications and ~/.local/share/applications.

Deleting the .desktop file corresponding to your program should remove its entry from Dash.

Actually, you should delete programs through Synaptic or Software center, but not simple by deleting the application folder. Also, you can delete the application icon from the unity dashboard by right-clicking it and than clicking on the "Unlock from Launcher".

To uninstall, simply open Ubuntu Software Center, search for the application you want to remove, and click "Remove".

thanks captain obvious – Nick Bailuc Feb 3 '14 at 17:43

I had the same issue, this seems to be quite a common problem. Ubuntu should include a MENU editor by default.

First I uninstalled the application, then I deleted all references from the following folder:

/usr/share/applications
/usr/local/share/applications
~/.local/share/applications

Rebooted....but never resolved my issue.

So installed this MENU editor:

sudo add-apt-repository ppa:caldas-lopes/ppa
sudo apt-get update
sudo apt-get install ezame

and delete unwanted icons.
