For what it's worth, I have uninstalled Avast from all of my machines. Not saying I'll never be back, but I am finished with the product for the foreseeable future.
Again, these big, intrusive, ads - and especially collusion with Google Chrome - were/was the deal breaker with me. In addition, the very latest update slowed my machines down somewhat too.
It appears that Avast is headed into obscurity along with the likes of Ad Aware, and Zone Alarm.
I've been computing for many years, and I have extensive background in CNC/CAD/CAM programming and machine operations, so I know a little bit about computers and code.
