I have uninstalled Symantec a long time ago, but there are still some leftovers remaining. Every time I start my computer, some dialogs will pop up and it's annoying.
There is no uninstallation entry in the Add/Remove program panel, so I cannot uninstall it using Windows tools.
I have downloaded the official Symantec removal tools, but the tool says that I have to first uninstall the software via Window's Add/Remove utility, which makes it a deadlock.
How do I clean these leftovers up?
