I’m sorry for the delayed response, as I had an emergency. Anyway, you mentioned that you’ve already uninstalled the apps, but they still appear as hidden icons in the system tray, correct? If so, they may simply be leftovers after the uninstallation, as some apps don’t completely remove all of their components when they’re uninstalled. In this case, you can try resetting the notification icons on the system tray by following the steps in the page below and see if it removes them.
