Never download anything from torrents without decent anti virus protection. A lot of people have some kind of utility installed but it is often really outdated or whatever. You can download AVG Anti Virus 2013 for free (I mean, legal free), it's a complete program and does its job very well indeed. Let it scan your system, I also advise to download the trial version of NOD32 to see what is wrong with your computer .nice on the netflix- they are giving a free month now so will get on that.
do you find that doin the torrent thing has caused your computer more problems? My ex downloaded a bunch and then my computer got slow and funky-
I used Netflix easily on my iPad when I was in town in November and December, watched the first two seasons of "Justified" (brilliant) and several BBC series.Do you have a Mac or PC? For Mac, get Automatic and you'll automatically download entire seasons of almost any show you want. It's great. On a PC, check out Torrent Episode Downloader.
Of course, there's also Netflix and Hulu. I just wrote a blog post about how to get the US versions of those sites in Argentina very easily on a pc, smartphone or tablet.
