fkr :
i left avg recently for comodo. i like to try new software.
but i believe if you double click on the avg icon in the tray then you will be able to select the buttons to activate any non functioning components.
if you are using the free edition only the antivirus parts will work
I don't think I understand what tray you mean, there 5 options that are all unactive, and when I try to scan I just get a blank page (dark blue actually duo to the color scheme of AVG)
And yes I am using AVG free.
