hi Steven. I'm Greg, an eleven years awarded MVP, Volunteer Moderator, and Independent Advisor here to help you until this is resolved.
Here's more about that infection:

What makes you think you're infected with it?
Download, install and run a full scan with the most powerful on-demand free scanner Malwarebytes:
https://www.malwarebytes.com/mwb-download/.
In the Malwarebytes Settings > Security tab set it to include scanning for Rootkits.
If necessary run it in Safe Mode with Networking, or Safe Mode accessed by one of these methods:

Clean up anything found, restart PC and then run again until it comes up clean.
Then download, install and run a full scan with AdwCleaner:

Check for any remainders in Settings > Apps > Apps & Features, and also in each of your browser's Extensions, Home Page settings, Search service or Add-On's as shown here:

Then check for damaged System files by running System File Checker from Step 10 in this checklist:
http://answers.microsoft.com/en-us/windows/wiki....
If completing all of Step 10 in above Checklist doesn't fix it then run a Repair Install which reinstalls WIndows while keeping your files, programs and most settings in place, by installing the Media Creation Tool from this link
http://windows.microsoft.com/en-us/windows-10/m..., open the tool and choose Upgrade This PC Now. This will solve most problems and also bring it up to the latest version which you need anyway and by the most stable method.
Strengthen your passwords for all financial institutions, Windows, your MS Account, your router password and Wifi key. An example of a password that is easy to remember is a childhood street address with a plus sign and then a childhood phone number that you remember - covers all bases and won't be forgotten.
Use two factor authentication wherever it's offered. In Windows it's here:

On the sites where this is at risk, ask their Customer Service how to protect your account to the greatest extent possible.
If you want to keep Malwarebytes as an on-demand scanner then you can turn off its Real Time trial version in it's Settings > Account Details 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.
