Welcome to our forum Jim. This issue has been solved. Please Uninstall the BullGuard application and reinstall it from Google Play Store. This will solve the storage use problem.
In order to uninstall it, you need to go to Settings > Security > Device administrators and uncheck BullGuard as a device administrator from there. This should be checked so BullGuard can work as intended, but when uninstalling this needs to be unchecked.
I apologize for any inconvenience this caused you!
