I downloaded the trial of Start 10, but uninstalled it but Defender (through the "action" center) notified me about the following:
I'm assuming it's a false positive since I trust that Stardock wouldn't put out malicious software but maybe something they want to check out with MS so that others don't get a bad feelign about it.
The following error occurred: Error code 0x80508023. The program could not find the malware and other potentially unwanted software on this computer.
Category: Trojan
Description: This program is dangerous and executes commands from an attacker.
Recommended action: Remove this software immediately.
