Random Network on My computer

Hello. Yesterday I was hacked somehow, where the hacker managed to get into all of my google accounts, facebook, etc and even after I changed my passwords they managed to get in (but were kicked out as I had set counter measures). Today Im looking through my computer because I suspect its a form of malware in the computer itself (since google was also telling me that), and I find a network (SMB) I had never made. Could this be the root cause of them being able to acquire my information so easily? Is there a way to get rid of such network I have no access to? I have completely restarted my computer (deleting Monterey, all of my drives, etc) but thats there.

Its important to mention that I had previously had bootcamp, where I think all of this originated from? Basically, im not sure on what they're doing, and im extremely desperate. Even if it isnt them who put the network, I want to get rid of it. Even if it means getting rid of my driver again, or doing whatever I need to do.
