I will be moving into an apartment in London in a year or so and would like to know what i will need to be safe (from virues and people steeling my bandwidth). My friend would move in with me so i would be using a rotuer to connect 2 macs and 1 PeeCee, the macs are both laptops so i will connect them wirelessly and the PC desktop would be connected via ethernet. What will i needto be safe. Should i get a software or hardware firewall? how can i be safe from someone trying to steel my bandwidth? I am not technical at all so i need help in this department. Thank you. EDITED: Do you know any fast ISPs in London with lots of bandwidth?
