Please feel free to contact us for any further assistance. Thank you.
Hi,
this file came today with the latest update of AVG 2011 (yes, it's old, but I didn't like the newer interfaces). "Force upgrade" makes me suspicious. There's no mention of this program update at
Install AVG on your PC, Mac | AVG installation files
Thanks
Okay John,
Thank you for understanding. Whenever there is a program update available it will show up and if you wish you can use it and install the latest version. Please feel free to contact us should you need any assistance.
Please see the subject line: 
It's AVG 2011.
