Go to your list of installed programs. (See SlackAlice's first post for how to get there). Look for anything labelled 'Musiclab', 'MediaBar', 'Wincore' or similar. If you find anything, click the option to uninstall it.
Then (irrespective of whether you've just uninstalled something or not) download the free version of Malwarebytes Anti-Malware:
https://www.malwarebytes.org/antimalware/
Once you've got the installation file on your computer, you need to double-click on it to start the installation. During the installation process you'll come across a pre-selected option to install a free trial of the (paid for) 'Premium' version. Remove the tick alongside that option before continuing.
When you got that program installed, run a scan with it. Don't be surprised if it takes ages to run. (I usually find that it takes well over half an hour. I've even seen some people reporting it as taking 2 hours to complete). It will almost certainly report that it's found malware. You then need to click the options to view, and then to remove, the results. (NB: I know that the layout of that program has changed a bit recently. If it's still basically same as the older version, you'll need to ensure that there's a tick alongside each item of malware found before you click the button to remove [or quarantine] them. If those ticks aren't in place it won't remove anything!)
