I'm currently also in the same boat. I use AVG IS at home (five licenses though will need to upgrade to eight soon) and also at work, on about 120 desktops. Have been a loyal supporter since 2004-ish and recommended it to many friends and family members and client companies when I was doing consulting. I've probably installed the paid for version on servers, desktops and laptops more than four hundred times.
My personal license expires in August of this year and the corporate in September/October. Because of the addition of "Family Safety," "LiveKive," "PC Analyzer," and the "Security Toolbar" with no way to remove them or disable their installation and no way to shut off the corporate up-sell in the control panel I am having to re-evaluate both my personal anti-virus/firewall software options and also the corporate one too.
I'm the key decision maker and have the power to sign the cheque on where the money goes so its kind of a bummer that this is what AVG is becoming. I'm going to hang in there until August to see if these issues are rectified but right now I am not holding out much hope that this will get fixed in time. I currently have one of my team evaluating other options, one of them being Avast! as it appears to offer the ability to do completely custom installs with a little tweaking of the installer scripts.
So what are you going to do about it AVG? Will you continue to cram in the up-sell for unwanted products on a product already paid for or will you listen to your customers and remove these (by default) on the commercial version of your software?
