Start11 odd behavior
popups on desktop

I have been a Start8/9/10/11 user for years, and only now have I seen something that confuses and concerns me. After installing Start11, every now and then I would see strange popups on my desktop (see image) related to a story from a website that I know for a fact I never visited. After months of troubleshooting, I narrowed it down to Start11 - when I uninstalled it, the issue stopped, when I reinstalled it, the issue began again. The random popup is annoying enough, but the idea that Start11 is linked to internet websites is troubling. It was enough for me to stop using the software altogether months ago, and the problem has never returned.
