I recently installed Avast! Home Edition. I've a couple of issues with it which are making it unsuitable... but I might be using it wrong:

1)Even a quick scan on c:\ is taking ages. I don't know which files it's scanning but I really just want to scan .exe files and everything in the Windows folders normally. I can't see options to control this.

2)When I turn of the on-access resident scanning, it always comes back on when I restart my PC. Can't I turn it off for good?

Is the professional version any different by the way, or just token differences?
