Hello, at first, sorry for my english, got an a bit weird question. Also im living in an very old House, in my Apartment theres no internet access point, so i share it with my Neighbor(he have router in hes Apartment), the Problem is, the walls are extreme Thick(so WIFI dont work at all) and the only way is through Ethernet Cable that going from my Apartment to the Router in my Neighbor Apartment. Now the question, i have also password on PC, using Win 10 with the Win Defender Firewall, have an VPN and all my file sharing options in control Panel are disabled, as much as i know, hes not a hacker but normal PC user, is there an big risk for me that he can access the Files on my PC? If yes, would be Comodo Firewall Free be better option than the Windows 10 build in Firewall?
