total security 2018 - 22.0.19.242
i previously added an application to the advanced threat defense whitelist, so i know it was working.
today i clicked add application to the whitelist - the add trusted application box popped up - i can navigate to the application and click on it. the OK button cannot be pressed as it is greyed out.
i did a reinstall of total security 2018 but the problem is still there.
at the moment i have the advanced threat defense turned of.
hopefully someone can help - thank you
