Windows 10: netstat -a reports many Established connections; is that bad?

When running netstat -a, I see many "established" connections to high address ports on my computer for example 49924. Should I be concerned? If so, what action should I take? I have McAfee on my computer and use a Netgear R7000 router. Thanks.

how to use netstat to check for malware?

netstat is a command-line tool (used from a

command prompt) that displays incoming and outgoing network connections, ports on which the computer is listening, routing tables, and a number of network interface statistics. It can be used to obtain Local/Foreign Addresses,
PID, listening state and for troubleshooting networking issues.

Lots Of Connections on netstat / Wireshark


So I haven't needed to netstat anything in a while and certainly never did on Win 10 but I don't remember so many active, established connections before.

I have established connections with Twitter, Pandora, Google, Microsoft, Linode Networks, Akamai, CloudFlare and probably a few others I haven't looked up just yet. Now I don't necessarily think most of these are a problem. Linode, Akamia and CloudFlare are the most questionable but they could easily be backbone type stuff Comcast uses, I don't know.

However, what makes me wonder is that the PID associated with these connections are connected to WebProxy.exe

Furthermore, Wireshark is actively communicating with most of the names I mentioned above that showed up in Netstat, even when no browser is open. I previously disabled Microsofts supposed settings that allow them to track your online usage but could this be part of something I missed? Do I just not recall correctly that all of my traffic should be going through a WebProxy? Should I still be talking to Twitter even though I am not on that website nor do I have a browser open?

I've noticed weird things and redirects every once in a while and I do a thorough cleanup which never produces much of anything (I am a tech who has cleaned up 100's of PC's, so it wasn't half azz).

Any thoughts would be appreciated.

 

Netstat -an showing lots of listening + established, why?


my friend was showing me how to do something on my computer and went on CMD, netstat -an .. it showed a lot of conections some where at TIME WAIT, most split between LISTENING and ESTABLISHED there are 74 i counted, is this something or nothing, tried to look it up online but didnt seem to get much telling me what should be there and shouldnt. i know its probably nothing but thought it would be worth an ask and hoped this may be the place for a quick simple awnser.
