I am using windows 10. my firewall turns off automatically at start up and Microsoft edge home page shows proxy setting error. I think I have malware as i downloaded some free software and since then this has been happening. But MCAfee did not detect any virus or malware. I tried to remove some files manually using task manager and i might have removed some important files as well. Please help. I have also run SFC/ scannow but no errors were detected. please help.
