Mega frustration. What the

am I doing wrong?
I'm finding that AVG Free is being blamed for preventing me from doing certain things.
It seems to be blocking the update of Service Pack 1 to my Vista Ultimate 64 bit on my desktop (though it has allowed SP1 onto Vista Home Premium on my laptop).
I'm also told, by Jeppesen, that it is preventing me from loading their software from proprietary CD Roms.
Both troubleshoots say "Temporarily disable virus scanner" - but I'm buggered if I can find a way to do it.
Brain fade, I'm sure - but when I try whatever I try - the most I seem to be able to do is to close the icon in the system tray (notification area - whatever it's called nowadays).
My next idea is to disable it with a sledgehammer - but I have a suspicion that doing so may make it harder to play solitaire, too.
PLEASE somebody - tell me what to click. Stoopid question, I know.
