I appreciate you getting back to us, ZGrant.
I know that this fake trojan scam popup has been keeping you from using QuickBooks seamlessly. However, the pop-up message you're getting has something to do with your computer. You might need help from an IT professional to help check the settings of your device.
If the pop-up is no longer there but you're still unable to work with the program, I'm leaving you this article that serves as a complete guide on the process of fixing freezing issues or when the software stops working: QuickBooks Desktop won't open, has stopped working, or not responding. This article may be for US but the steps is applicable to AU.
Reach out o me anytime you need help with QuickBooks. I'm always here to help. Have a good day.
