Just updated from the UI on mu win7 netbook - avast free 8.0.1497. Things progressed well albeit pretty slow program update.
First point of note my firewall Outpost Firewall Pro, reported unsigned kernel mode driver !
Secondary point of note, after the reboot the avast free antivirus Setup screen is bloody massive, it won't fit on my 1024x600 screen. You can barely see the first opt out for chrome checkbox and you can't see the second nor can you see the Continue button.
This causes lots of hassle as the screen can't be resized, nor can it be moved up to click the Continue button as when you release the mouse pointer (after dragging the screen up) the window goes back to where it was. Now it is a case of trying to use the tab key to highlight the button that you can't see.
A right pain and possibly going to have people get chrome again.
