1) I tried going to
www.support.avast.com but, unlike other Avast pages, it won't present trusted identification and Firefox thinks someone is tampering with my connection. Is this normal?
2) The computer I've been using (which uses Windows 7 and, I think, Avast Pro) won't recognise it's network connection at the moment. I have an old pc (Windows XP and Avast Free) and just got a Windows 8 pc. I want to get all 3 covered by a suitable version of Avast as the price for doing all 3 is competitive. Is there a page which compares Avast Pro, Internet Security and Premier?
https://www.avast.com/index compares the Free, Internet Security and Premier versions but it doesn't include Pro and right now I'm having trouble finding a page which lists what's included in the Pro package.
3) How do I have to do the installation when purchasing for more than one computer at once? At the moment I only have one screen, so I can only have one pc running at a time. I don't want to buy for three and then find I can only set it up on one.
4) Would there be any complications caused by already having Pro on my Windows 7 computer? I believe I paid the subscription in October but it works out more cost-effective to buy for three at the same time.
Thank you for any help you can give and sorry if I'm having a "senior" spell.
