The same thing happened to me shortly after I moved to a Mac. I made the same mistake you probably did: I ran Firefox from its.dmg file, and every time I ran it, the.dmg re-opened on my desktop.
The way to install an application on a Mac (once you have downloaded it) is to:. Open its.dmg. Drag the application file inside it to your or the system's applications folder. Drag the application's icon from the application folder (not from the.dmg) to the dock, if you want it there. Right-click or cmd-click the.dmg file and eject it.

Delete the.dmg file - it was just a shipping container.For your currently sort-of-installed Skype, right click the Skype icon on the dock, select options, and uncheck 'Open at Login'. Drag the Skype icon off the dock (it goes poof! And disappears). Re-do the install as above.
If you want it to start whenever you log in, use the dock icon again to select that option. Look for Skype in System Preferences Accounts , on the Login Items tab, in the list of applications to be run at startup. (This is the likely 'Autostart' place).
If you find it there, right click it and and select Reveal in Finder. That should show you where Skype is being loaded from, if it's not from the installed application (maybe it's still being loaded from the.dmg in the trash). If you find it is being loaded from somewhere other than your or the system's Applications folder, delete it from the Login Items list to be continued.–Sep 25 '10 at 15:31. I had a similar issue with a DMG file sitting in Places within my Finder. I couldn't seem to delete or remove the file - regardless of what I did. Same as the person above, when I right clicked on the item, it brought up the preferences for finder. If I double clicked on the item, it told me that it couldn't find the file.I am assuming that somewhere along the line, I installed the software, somehow dragged the.dmg file into the places section and then had deleted / ejected the original DMG File - leaving the file in my places.After thinking about it a bit, I went searching for the original file on the net which I strangely couldn't find.
It was some random installer for WebEx software that I think auto installed when I participated in a webex conference.So, I tried to trick it. I renamed another.dmg file to the same name as the ghost file and then double clicked to open it. The.dmg file showed up in my 'devices' section - actually with the correct.dmg info, not the renamed file.HOWEVER, now when I right clicked on the ghost file, it gave me the option to remove the item from the sidebar - which is what I wanted to do. I then ejected the.dmg file and problem solved.
As far as I know, the only way to properly create a bootable Lion disc/disk is to use Disk Utility on a working Mac. However, the other option is to use a VM to run OS X temporarily (scroll down for that info). On a Mac:.Download Lion from the Mac App Store. The installer should show up in your Applications folder.Right-click on the installer and hit 'Show Package Contents'. Navigate to Contents SharedSupport and look for a file called 'InstallESD.dmg'.Open up Disk Utility and drag the DMG file into the left-hand sidebar.
If you're burning it to a DVD, insert your DVD, select the disk image in the sidebar, and hit the 'Burn' button. Skip down to the last step to use it.If you want to burn Lion to a USB flash drive, plug it in and click on it in the left-hand sidebar in Disk Utility.
Go to the Partition tab and select '1 Partition' from the dropdown menu. Choose 'Mac OS Extended (Journaled) on the left.Hit the Options button under the partition table and choose 'GUID Partition Table'. You'll need this to make the drive bootable on a Mac. Hit the Apply button when you're done to format your drive (note: it will erase everything on the drive).Click on the 'Restore' tab, choose the InstallESD.dmg file as the source and your flash drive as the destination. Hit the Apply button and it will create your bootable USB drive.Reboot into OS X and hold the option key when you hear the startup chime.

You can boot into your DVD or flash drive from there.On a PCI know this works with Snow Leopard, but I'm not sure about booting Lion in Virtualbox.
