Thank you.

I installed Chrome from Windows Store to my Win10 Surface Pro3. It appears as a Chromium app with Yahoo! piggybcked on it. On every restart they appear as two uninvited windows about 20 seconds after I restart. File location is hidden. Disabled start-up, but can't remove. This not the Chrome we use on Android devices. Is it a virus? AVG so far does not identify these as a virus. How to eliminate?
