I have recently been having problems registering Avast Free on client PCs.
Last week I "converted" another client to Avast, only to find that the registration page had changed, and that the "continue" button wasn't working. Having told my customer what a great product Avast was, this was slightly embarrassing. Having had this problem on the odd occasion in the past, I explained that it was probably just a server error, and that it would probably work in the next day or so. Yesterday I installed Avast on a neighbour's laptop after replacing the LCD panel. Again, the "continue" button didn't work. In the end I carried out an email registration for him, which reminded me of much earlier versions of Avast. I am now wondering if existing users of Avast Free will have this problem when they come to re-register after 12 months.
I understand that Avast Software is a business, not a charity. However, I assume that the Free version is provided as a huge advert for the paid products. It doesn't create a very good impression on potential customers when they encounter problems early on with a product. If Avast Software don't want to continue providing a free version, then I suggest they stop doing so, instead of being "underhanded" in trying to get people to pay.
