Phishing

If you did a clean install you are fine. (and by that I mean you deleted all partitions on drive and scanned your data with a tool like MalwareBytes from MalwareBytes.com) Any software they would have installed is gone. Your router will ignore packets that appear if they did not originate from a computer inside your network.

Not sure what you use for a router or if you are using the default router password. This is an extreme case. You can Google "Malware on Routers". If you are concerned you could reset the router so it reloads base firmware. (Clean install). Now if this is a supplier modem router you could ask them to reset. In any case the default router password should always be changed. Write it on a piece of tape and stick to bottom of router so it's always handy. I always use my own router, even if supplier supplies one and first thing I do is change password.

Now as I said this is an extreme case, most malware outfits are not that sophisticated and there are plenty of fish out there so they just move on.

Edit: We didn't discuss identity theft. If you let them on they could have copied some data. I would be changing all financial passwords at a minimum and I would just put a little extra effort into watching accounts. Not to raise fear level. Just do it as a precaution.

It's not paranoid. You can't tell what they are doing in the background. A clean install is the answer.

I got phished about a month ago by an Indian outfit. They trailed an HP printer driver installation page I was trying to use for a new printer, and place a "chat" ear at the bottom of the page. After I could not find what I was looking for, I clicked on the chat ear and the rest is history.
I ended up wiping my machine clean.
I reinstalled windows 10.
I want to know if I am still at risk from these people.
Do I need to change my IP Address? If so, how?
What else do I need to do?

Hi.
Glad you wiped the machine - that's the only sure way to be rid of whatever they did, once they've been in your system.
Ken is right - all passwords should be changed from a known-clean system. You have to assume that, once they were in, a silent script was run to collect all kinds of data from your machine, especially passwords.

Sorry you had to go through this. In the future, a Macrium image would have been a quicker solution to restore the system; then the chore of changing passwords would only have had to be done..
