These are some how to articles which may help with using TCPView.
There are other third party utilities that will allow you to manage, block, and view detailed listings of all TCP and UDP endpoints on your system, including local/remote IP addresses, state of TCP connections and the process that opened the port:Caution: If you're going to start blocking ports, be careful which ones you block or you may lose Internet connectivity.
Some legitimate programs on your computer have access to the Internet and that action can trigger an alert but your firewall should be able to give you a list of such programs so you can confirm if they are legitimate. If your firewall provides an alert
which indicates it has blocked access to a port
or detected an intrusion attempt that does not necessarily mean your system has been compromised. These alert messages are a response to unrequested traffic from remote computers
(an external host) to access a port on your computer. Alerts are often classified by the network port they arrive on, and they allow the firewall to notify you in various ways about possible penetration and intrusion attempts on your computer. It is not unusual
for a firewall and some anti-virus programs to provide numerous alerts regarding probing and intrustion attempts. However, not all unrequested traffic is malevolent. Even your ISP will send out regular checks to see if your computer is still there, so you may need to investigate an attempted intrusion.
Malwarebytes Anti-Malware IP Protection
(malicious website blocking) is part of the Protection Module
and works after it is enabled. When attempting to go to a potential malicious website, Malwarebytes will block the attempt and provide an alert. Some legitimate programs on your computer have access to the Internet and that action can also trigger an IP alert. These events are stored in the "protection-log". Your firewall should be able to give you a list of such programs so you can confirm if they are legitimate. IP Protection is also designed to block incoming connections
it determines to be malicious. Botnets
and Zombie computers
scour the net, randomly scanning a block of IP addresses, searching for vulnerable ports
- commonly probed ports
and make repeated attempts to access them. Hackers use "port scanning
", a popular reconnaissance technique, to search for vulnerable computers with open ports using IP addresses or a group of random IP address ranges so they can break in and install malicious programs. Malwarebytes is doing its job by blocking this kind of traffic and alerting you about these intrusion attempts.

What does IP Protection do?
IP Protection provides an additional layer of security for your computer, by preventing access to known malicious IP addresses and IP ranges...
What does this notification mean?
This notification means quite simply, that an IP address has been blocked. It does NOT necessarily mean you are infected, it simply means a program on your computer (e.g. your browser, IM program, P2P program etc), tried accessing a malicious IP address...

If you are using peer-to-peer (P2P) file sharing
programs (i.e. Limewire, eMule, Kontiki, BitTorrent, uTorrent, BitLord, BitLord, BearShare, Azureus/Vuze, etc) or an Instant messaging
(IM) client, be aware they can trigger IP Protection alerts. Why?
Because these kind of programs are a security risk which can make your system susceptible to a smörgåsbord of malware infections
and remote attacks. Even the safest P2P file sharing programs that do not contain bundled spyware, still expose you to risks because of the very nature of the P2P file sharing process. By default, most P2P file sharing programs are configured to automatically launch at startup. They are also configured to allow other P2P users on the same network open access to a shared directory on your computer.
