ROBoSaAvero is just an ad application that displays invasive ads with the possibility of installing malware. I suggest you try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
Run AdwCleaner two times in a row to make sure the application is removed completely from your computer.
