I just google Google in bing and then put it in favorites because I like Google better. Both have spyware the sell to see what you googling to buy, this is why you get all the popups. I searched one product In each, the ran antivirus software and came up with 29 threats and 24 threats. These threats are stored on your computer and run in the background, all FREE sites have their spyware the sell. It's how the make millions hence FB, Tweet, Google, when you enter there sites you are protential customers for the various sponsors.
I also think hackers are on the antivirus company payrolls, the more hacks the more pontiental customers?

it like selling triple bladed razor, after the blades dull you have to buy the expensive triple blades with the big gouge, it's how they make the big money! Maintenance
