To remove BubbleDock, install AdwCleaner and perform a scan. If it's not detected, run a scan session with Combofix and wait until the scan log pops out. It should display that the BubbleDock was removed successfully.
Combofix will restart the computer in case it's required. Once the computer boots back, the scanning procedure should resume. The Internet and other 3rd party applications will be turned off and closed.
