Please upload a copy of your system information file. Click "start" , type "msinfo32" , Click "file" at the top of the page, select "export" and give the file a name and click "save" .

Navigate to where the file was saved to, and upload the generated text file to a public folder on your OneDrive account and post the link here.

Meanwhile,

Download, install update and run a complete scan with Malwarebytes (free version).

Malwarebytes.

Note:

decline, the "free trial" offer, just prior to launching Malwarebytes, if you are inclined to do so, but remember, accepting the offer, lauches the program in full mode and that includes real-time monitoring that may cause a conflict, if you already have another AV Product installed.

Remove any and all found objects, reboot and repeat, until there are no fyrther detections.

You may also, want to run ADWCleaner, for good measure.
