Question about my TV talking to my computer?

edit

So I am Information Security graduate not currently active in the field(graduated in 2012 and left the field in 2014).I'm always researching my network to keep my interest going. Anyways my knowledge with wireshark isn't up to par, but I know enough to be dangerous. I have wiped my computer several times as well as devices in my house, because I believe someone is messing around in my network. So I have a Vizio TV that has been sending interesting traffic to the main computer I use and I hope posting here will give me some answers. I believe the hacker is operating off of 'containers' or my Linux partition on my computer because I see my nvidia software using containers as well as finding some in my linux partition when i log in. We will start with the basics and go from there. I have blocked my TV on my software firewall for my computer. Please tell me what exactly is going on here. Any information/feedback/brainstorming is greatly appreciated. I just want my network safe again. This is a UDP stream from the TV(192.168.1.188) trying to communicate with my main computer.

EDIT: I did a nmap scan on my Vizio TV and it has the following ports open

TCP - 7000 - afs3- fileserver
TCP - 8007 - http
TCP - 8009 - ajp13
TCP - 8443 - https-alt
TCP - 9080 - glrpc

all syn-ack

Let me know if you need anymore info on the packets I have captured.

Thanks a ton everyone!
