I have installed Norton Security & Antivirus (Norton Mobile), free edition, on my Nexus 7 tablet. The Google Play Store shows this app is designed for phones, but it does appear to be running on my tablet. I have started receiving notifications of "apps with issues found" but when I open Norton Mobile, it does not show the affected app. By chance, I found my library app, when opened, has a red strike-through over https showing a certificate error, but I only discovered this by accident. How do I find out which of my installed apps Norton Mobile is referring to?
