Just a quick question, I'm not sure if this has already been asked & answered before. Did have a quick look on the search but didn't find anything relevant.
But anyway, what I'm wondering is what is the actual difference between downloading Avast off of
www.download.com for free, & getting a registration key that will allow me to use Avast for 1 year at no cost; compared to the Avast that I would have to pay £25 so that I can use it for a year? I've got the free edition on my friends laptop, & I'm currently using the demo of pro which lasts for 60 days, but I haven't seen any differences between either of them so far.
