I have never seen this behaviour on the Mac but I would take a number of steps
1. Go to System Preferences Security and the General and after clicking the lock to make changes make sure that you can download apps from anywhere. 2. I would then go to Disk Utility and perform a disk permission repair on your hard drive. You will be able to get to the Utilities folder in Finder by pressing command shift U. Ideally you should do all this in the recovery console but try in Disk Utility first. 3. You could then review your apps folder to see if VLC has reappeared. If not install one more time but I would restart your Mac before making this install. 4. It is normal to get the warning dialogue you describe but you can normally navigate it. Hopefully a restart will sort this. Otherwise try pressing tab to navigate rather than vo cursor and pressing space bar on continue if you can get there. On any button if vo space does not work it is worth trying space or ever on it.
