I like to call it the Shareholder death spiral. Shareholders want more dividends, making a quality product and keeping up with the current threats takes a back seat to marketing and adding as much bloated "Added product value" as possible, until eventually the antivirus is so bloated it slows your computer down. As insult to injury, around this time it will also start displaying a dialog box that you can't get rid of, containing an advertisement the devs based on a "system optimizer" malware they saw a few weeks ago- with a little bit of customization detailing how it can speed uptheir shareholder earningsyour computer for you if you just buy this one extra feature.
