Thanks for your reply. However, things are getting a bit confusing. My Windows Firewall is disabled --- my Avast! clearly says it has a Firewall and presents me with various options for it. I have found where to turn it on or off, which answers my original question. What I do not know is the status of my 'subscription' ---I cannot find anywhere that tells me what level of protection I have. I would have thought the Account page would have information on this, but it appears not to. I thought it was the minimum, Free Edition, and have no recollection of paying for it --- and am surprised if I did, for reasons I wont go into now apart from the fact that Avast! offers well recommended free program .
I have a licence running from January 2015. If I interpret it correctly one page says I have a licence for one device which as far as I am concerned is correct, it is my 'old computer' a Windows XP, still working but not very well, very sluggish and prone to freezing. My 'main computer' is a new Windows 8.1 Tablet which I am using at the moment and which has a different malware program (the full works) . But other pages on the Avast! website sayI do not have any devices registered and keep prompting me to download a program I already have, and 'register my first device.'
So I am not sure exactly where I stand. What I need to know now is (a) what version of Avast! I have (b) do I need to re-register my XP computer (c) what are the implications of turning off the Avast! Firewall for, say, 15 minutes while I transfer some photos to the Digital Frame?
