Avast loads breathtakingly slow at start up

I have the most current Avast ver through update, but this has been an issue for a while. When I start the laptop, everything loads in a decent time, but Avast takes easily a minute further to load. I went into startup, Local Services, &c, and disabled everything that was nonessential. This made no difference.

Any suggestions? Ie, HELP!

What OS/SP ?
What exact version of avast ?
Any other security (related) software installed ? (or was there)
Already performed a repair of avast ?
Already performed a clean installation of avast ?
What else is loading at boot time ?
etc

I wonder if it was doing a route scan or was the computer set to do a Disc Scan?
