ok so ive noticed this for a while now that my system gets progressively more sluggish and slow to respond as i use it through the day (particularly when doing heavy browsing) I never really noticed this happening until i installed v6 of avast and i figured avast is quite possibly the reason for it. So after disabling all of avasts shields my computer immediately became MUCH more responsive and the sluggishness was basically completely gone.
This is pretty serious for me because the sole reason i had moved to avast originally was its speed and i will have to ditch avast unless this problem can be solved.
