avast and chrome speed issue

hi all - first time posting here.

i have been a chrome buff ever since firefox kept crashing. and i have been an Avast fan ever since i abandoned AVG (and norton before that)

my problem: i recently reloaded the win-7-OS on a nice new fresh solid-state drive (read: no other antiviruses were installed there)

recently i have noticed when i first boot up and start chrome, the drive-activity light just goes on and stays on for the first 10 minutes or so after boot-up. there just seems to be a constant drive activity.

i can fix this by either removing chrome OR avast.

right now, i am using firefox again, with chrome removed, no problem.

has anybody ran into an issue where chrome and avast seem to cause constant drive activity?

NOTE: i have ordered a even newer FASTER ssd, so i am going to reinstall the win-7 OS yet again either way…

(update - i did try Procmon… that’s how i figured out it was the relationship between chrome and Avast)
