Issue with Avast at bootup

[dale79]

I have Avast Internet Security.  When I reboot my machine it takes over 10 minutes. There is a long period when nothing is happening except the hard drive is being accessed constantly.  Does Avast run a full scan every time Windows reboots?  Is this what is causing this activity / delay?
If it is not Avast, does anyone have any idea what it would be?

If so, how do I disable this activity?  I cannot have it taking 10 minutes every time I reboot.

What Operating System? Are you doing a restart or, shutting it off and then back on

Windows 7 Ultimate. OS system restart.  But, it is the same whether it is a restart or a power on.
