Muahah, I know what you mean. Way back then, I hated viruses, and I was so scared of them. I wasn't necissarily not allowed to DL stuff, however I knew I'd get in a heap of trouble if I got a virus!
Anyway, yes. uTorrent is a virus-free and safe download, especially if you already have some virus-eating software. So don't worry, you will be able to get the maps without any issues of a virus :]
Enjoy the maps!
