Why have avast no monthly subscription option? I can't afford to buy a whole year at once, but I could easily split that money into 12 and pay once every month. The subscription could be an optional way of payment, so if someone buys a year, uses 3 months and then cancels the subscription, then his next bill would be the rest of the money he owes avast.
EDIT: I seems to be the only one that wants this option...
