As you can see in my sig and profile, i have used avast since 2004 if i am not wrong this was the year of 4.1.418
Since the first time i have it installed I see the diferences beetwen avast and others av
_ Modulate structures
So you can configure each module of the program as you want

Many updates in a day

THE ABILITY OF FOUND AND CLEAN THE INFECTIONS WITHOUT ANY INTERVENTIONS OF THE USER(you dont need to click on the file to test it ,as many av which you MUST TO CLICK THE FILE in order to check it against infections

The ability of automatically check a file is NOT PRESENT UNTIL NOW IN MANY AV PROGRAMS

before the release of ais as i wanted for a security suite, i move from avast free to suites like kis, (kaspersky), pctis(pctools) and kpure(kaspersky pure)
But i was only waiting for ais release

Avast is the best of the world
