After dumping McAfee and installing Avast 4.7 Home Edition on my Vista Home Prem 32bit laptop, I immediately right clicked the Avast icon in the system tray and clicked to manually update the iAVS. On my Win98 SE machine, a green and brown icon would appear and show the update progress, but no such icon ever showed up in this case.
I did check my settings and checked to show an icon while an update was in progress, but this facilitated no change when I attempted it again. The program eventually updated itself automatically, but I like the control of manual updates.
Thank you.
