Weird updates "Security Threat Intelligence" on desktop

Hi Mo,

Welcome to the community!

The "Security Threat Intelligence" updates are a standard part of Windows Defender and are meant to enhance security by providing real time threat intelligence to detect potential attacks. These updates shouldn't cause odd behaviors like what you’re seeing, but sometimes they can trigger system processes or conflicts, especially if they interact with virtual machines or other security software. If the associated URL is inaccessible, it might be a temporary issue with the update or your network. It's unlikely related to anything malicious, but if the behavior continues, you might want to check for any conflicting software or update your virtual machine drivers in case they may be affecting in some way. 

Regards
