dUninstaller as you may know has uninstall definitions functionality that is treated as a wildcard search term, case insensitive. So you could in theory put “toolbar” in the definitions, and any installer entry with “toolbar” in the name will be uninstalled. The downside is you may end up uninstalling legitimate toolbars you wish to leave installed.
Now with the whitelist functionality, you can whitelist legitimate apps, and just the same as the uninstall definitions it is treated as a wildcard search term, case insensitive. So you could put “bing” in the whitelist, with “toolbar” in the uninstall definitions, and it would uninstall everything with “toolbar” in the name except anything with “bing” in the name.
This functionality should be added to the stand-alone version of dUninstaller soon. Currently it is only available in d7II v1.7
