Hey Ditto. I'm Greg, an installation specialist, 9 year Windows MVP and Independent Advisor, here to help you.
Run a full scan with the most powerful on-demand free scanner Malwarebytes:
https://www.malwarebytes.com/mwb-download/
Clean up anything found, restart PC and then run again until it comes up clean.
Check for any remainders in Settings > Apps > Apps & Features, and also in each of your browser's Extensions or Add-On's as shown here: https://community.box.com/t5/How-to-Guides-for-...
Then check for damaged System Files: https://www.lifewire.com/how-to-use-sfc-scannow...
If it cannot repair them see Step 10 here to continue: http://answers.microsoft.com/en-us/windows/wiki...
If after all of these steps anything remains then see these additional removal steps:

If you want to keep Malwarebytes as an on-demand scanner then you can disable its Real Time trial version in it's Settings > Accounts tab.
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
