Hello Elmo and welcome to forums !!! You just found best forum in the world...
Just listen my friend's (Technical) advice and everything will be great. You just need to register online (it's free, no obligations at all) and shortly, you'll get registry key for your copy of avast! home edition, which is btw, best antivirus ever !!! That registry key is valid for one year, and after that you'll need to reregister, just like rest of us...
Regarding avast! Pro version... of course if you want Pro version you'll have to pay for it... that's the way it should be. We have to reward Alwil guys for making such a great product.
Anyway, welcome again and I'm glad so many Canadians started to use this great antivirus... btw, I'm from Toronto, Ontario. Hope you like all those skins available in avast! skins download section... Link:
