GlobalProtect

For those of us who are MSFT employees, don't be afraid to call IT when you see something that looks like malware. I did and spoke to a guy who explained to me that this is indeed legit, and is being rolled out internally to support a new VPN option. Don't take my word for it though. It could easily have been malware, so you skeptics were right to worry. Call IT and, in this case, just get the link to the FAQ. (Two stars because it really does look like malware. Bad branding, unknown signing party, lots of 1 star reviews. Do better, Microsoft.)

Like others have mentioned, this app launches the store with a link to itself. Microsoft, please investigate

Windows store popped up on its own with this app's page without any actions from my side.

This app appeared on my computer. No matter how many times I uninstall it; it comes back. I'd wipe my machine however I'm afraid this may be a store issue.
