You need a higher standard of evidence. A buffer overflow could root your computer.

Also, I don't believe that you've never downloaded anything - can you show us a screenshot of your installed software?

Then why mention that your PC can't have been compromised?

You're making a big accusation, and I want to see some more evidence. You claimed never to have downloaded anything, which is unlikely to say the least.

1. Can you provide the screenshot of installed apps?

2. Also, let's see the full ip.

I won't show the full IP until I can mirror that report somehow.
