So after first using VIPRE antivirus and then BitDefender I have decided to use Windows Defender. After uninstalling my previous AV program I realized that Windows Defender Real-time Protection will not turn on. On the Windows Defender start page it states "Windows Defender Real-time protection is off because you are using another AV program. Uninstall your existing AV program to turn on Windows Defender." I currently do not have another AV program installed. I suspect it is due to a messy uninstall of VIPRE Antivirus, however I was very specific in following all steps to manually uninstall VIPRE using the registry editor.
I have searched through the community and tried numerous methods to fix this issue, but so far none have been successful.
Is there anyway to force Windows Defender to recognize that I do not currently have a AV program installed?
