Is there anyway to stop bytes coming in and out without shutting down

internet connection?

I keep getting small packets of downloads and uploads even when I got no browser open or when I'm not downloading anything.

I looked up in my comodo firewall incoming and outgoing connections and:

It seems that they are causing it? These processes, mainly chrome causing the most usage.

I wonder why Chrome does it? I mean if I close the browser why does it keep downloading bytes?

My goal is to preserve as much bandwidth as possible. And I'd prefer not to disable my internet each time I don't need it for a duration of time.

It would be easier to stop these bytes in and out without doing that. I don't want them to stop forever just for a period of time. I understand these programs need to communicate with their servers online or so but not all the time...

use a packet sniffer see what the traffic is?

Thank you for helping me search in the right direction for a solution!

No idea about Chrome exactly (never used it), but always remember that visually closing a program's window doesn't necesarily means that the process is terminated, but I can't come with a reasonable fact on why it keeps some data transference, maybe automatic updates checking. Verifying the target IP of those might uncover something else.

About Avira, it's easy to think on automatic database update or something like that. Disabling autoupdates may stop those connections.

Svchost is a whole can of worms, as many built-in Windows services run as it. From memory, the ones that reasonably access network are time service, automatic Windows updates, WER "reporting" and maybe BITS working on behalf of another program. All of those can be disabled to preserve bandwidth, or at least to configure when to consume resources.

Since you're already using a firewall, I may also recomend to configure it to aggresively block any unwanted connection and program that isn't supposed to access the network. There are really few things that absolutely require internet access, and even less that legitimaly need to call their own servers.
