Hi,
I recommend you do an analysis with Microsoft's MSRT, analyze Windows Defend Offline, Malwarebytes and Adwcleaner
MSRT

Microsoft Defend:
After the analysis, open the command prompt (admin) and run the commands: sfc /scannow and dism /online /cleanup-image /restorehealth, wait for the process to finish and restart the computer.
Then perform a clean boot and if you want to uninstall applications that you do not use.
Thanks
