Hi every1 I have a housemate who is a bandwidth hog. His PC is on 24/7 downloading torrents in the background, downloading everything from dvd rips, music to vast amounts of porn. He doesn't have good internet etiquette or sensible browsing habits, and has had to reformat his Windows-based computer several times this year because it has become so infested with viruses and malware it literally grinds to a halt. Should I be concerned about the level of threat this could mean for other people's computers in the household, including my Mac? I recently replaced our Airport Extreme with a Time Capsule. Because our wifi is delivered through the Time Capsule, and thanks to my housemate has a constant flow of torrents coming through it (his torrents alone download at an average speed 448.89KB/s), could my Time Machine backups stored on the Time Capsule be at an increased risk of being hacked? I've tried talking to him about it on numerous occasions but he says I'm being paranoid. Our ISP is Virgin Media in the UK and we don't have a bandwidth cap, it's just the security I'm mainly concerned about.
