Lay down with dogs, expect fleabites.
If you are going to use tools such as BitTorrent, which attract the scum, then expect nasty things to happen to your systems. I use different systems for different uses, with reading potentially dodgy websites or testing potentially dodgy applications reserved for an old Linux PC with a small hard-drive I can rip and replace for a few bucks. That effectively keeps any nasties air-gapped from the systems I use for work and play. For a while I did have a VM set up for such purposes but it was more hassle than it was worth so I went the old PC route (forty quid off eBay).
