I think someone somehow managed to gain remote access to my computer and was able to log into my ebay account and purchase some stuff. I was noticed the suspicious activity, and yanked the power cord, but I don't know how long they were in there before trying to make the purchases.
The way I understand it, there's no way to be sure they didn't do something else, and my best bet is to nuke it and start over.
- So the question. How far do I need to go to be sure?
- It's Windows 10, so can I just do a reset of Windows erasing everything?
- Should I reformat completely?
- Buy a new HD?
I have Windows installed on one drive, and most of my important files on another drive, so I don't know if that will affect anything...
Edit:
I was at work, and got a notification on my phone about an ebay order. I checked ebay and saw there was a purchase for gift cards by email. I checked PayPal and there was a charge. I called ebay first and was told it was made though one of my devices. I called PayPal and reported the fraud to stop the payment, and the bank to block it. I checked my email and someone had put a filter in to send eBay and PayPal email to the trash. I have two factor on my gmail, unless it's one of my trusted computers, which means my home or work.
After I figured that out I called the wife and had her yank the plug after looking at the screen. A program I had left open was no longer running.
Also I tried remoting into my home computer from work through teamviewer, but it wasn't available for some reason. I half wondered if someone got in that way.

Did they establish which device? Focus seems to be on the home PC, but you also sayI have two factor on my gmail, unless it's one of my trusted computers, which means my home or work.
Business networks and work computers are not necessarily immune to hacking. Not saying that's the case, just that technically it's a possibility until provably excluded.
