Settings indicates that my F-Secure antivirus is switched off and Defender is switched on. When I open the F-secure app it is shown as fully active - I thought that running two AV programs at the same time was problematic. There seems no way to switch defender off and keep F-Secure on as Windows 10 seems to believe that F-Secure is off. I am currently having difficulty installing a new program, which might be caused by an AV program conflict. What should I do?
