“Your computer might be at risk”

That extra detail made it very realistic.

Came here to say this.

As soon as it popped up, I was like; oh, shit, yup - there it is.

WinAmp and it's fantastically on-point UI-mockup and functionality was also a super nice touch.

tbh I still use Windows XP SP3 in my VM on my Mac for the occasional Windows utility I need. It's super no-cruft and lightweight - especially as a VM - compared to anything since - and is surprisingly compatible. Because it's in a VM, I'm not too worried about the security issues, and most of the Windows-only utilities I use are fairly archaic anyway. (In computer years)
