I get a notice that Firefox wants to update. I click go ahead. My Webroot Secure pops up to state there is a risk of infection and denotes it as pua. something or other. Is this a real threat or is Firefox attempting a legitimate update? I just installed it two days ago from your website.

But does firefox do the updates in the background, without any popup windows? If so, then when I see a popup purporting to update firefox, I will know it is fake and let my AV do what it asks to do - get rid of it. The name of the threat was pua.firefoxadmin or something like that. On the other hand, if there is a setting stipulating that I always be asked (I thought I asked at install that firefox just do the update automatically) and this creates a popup, I will allow the update.

How do I check to see if I am being notified of each update and asked to approve?
