Anyone have any idea what all the activity was and what can I do in the future to identify the activity. This apparent download lasted over an hour.
If you are using typical cable modem or DSL ISP arrangements, there's just lots of random external activity on the WAN side of the router, most/all of it worthless network traffic. Perhaps some of it is "malicious", seeking out unprotected machines to do who knows what to them.
If you had a software product that could log and present to you the source IP addresses you would know none of them.
All of it is "foiled" by the firewall in your router, or in the absence of a router by Windows Firewall or other software firewall products.
It's annoying to see all of this, especially if you didn't have a router and your machine itself would need to simply reject all of this nonsense traffic via software (and your machine's CPU resources). Unfortunately it is "perfectly normal" and there's nothing you can do about it.
Not to worry, especially if you've double-checked with Task Manager what your machine is actually doing and it showed nothing active or unusual. That's why you have a router... to protect you from this nonsense.
