My apologies. I'm using Avast internet security paid version. Laptop has 2 quad core 3.2 ghz processors, 64GB ram, 512Sata SSD and 2TB platter SSD. Nothing in the task manager is obtrusive or obnoxious. Firefox tends to suck up memory especially when I have a ton of tabs open, BUT, even though I leave the laptop on, I usually kill Firefox when I am done for the day. That being said there doesn't seem to be any difference in Avast locking internet traffic whether I have left FF open or not -it seems to happen ever 3-4 days.
