Far too many pop-up advertsEvery day and, seemingly every couple of hours, there another "opportunity" to spend more money with Avast. "This isn't secure... that isn't secure... spend, spend, spend... or the baddies will get you!" It used to be that anti-virus software had one job to do: protect the client and his/her computer. Now it's more like Mafia fire insurance, or protection money. The baddies may not hold you to ransom, but Avast will! I've been using Avast since 2003 and I trust it to do a good job of preventing virus infection - but I wish they had a reasonable tarrif scheme which was upfront rather than: "Just another $20 here, sir, and you'll be safe... just another $30 here, sir, and you'll be safe...". Just provide a bullet proof service for a decent sum of money. Stop constantly up-selling. Because, the truth is, if your client's aren't protected from the very start, and you just incrementally increase your prices, then you aren't really serving the customer's needs, your are serving your own.
