Hello again Igor,
sorry if I have confused you. It is me at fault.
When I look at about avast from ball in system tray. I see that it says.
build nov2004 (4.5.512) avast version4.5 home edition. so it seems I have this but not installed. Not sure about this. How do I tell if I actually have 4.5 working?
It is when I choose update in menu I freeze up my comp. and system tray icons go missing.
Is it best if you send me the installer link or uninstall and get back to 4.1.
How do you send the link?
Thanks again Mal
