Thanks for this clear breakdown; I’ve seen this O16Setup.EXE file pop up on a few legacy systems lately, and your distinction between the legitimate Office components and potential malware is really helpful. It’s always tricky when installation files mimic standard naming conventions, so the community poll here is a great way to gauge the risk level. I’ll definitely be pointing my team to this guide the next time we run into mysterious background processes during our server maintenance.
