On the suggestion/advice of someone here, I decided to try some downloads to help clean/speed-up my PC. Most of them I don't know how to use (or don't know if they are working) - and one in particular says I need to download a "torrent" or "bittorrent client". What the heck is that (?) - it seems like just more junk (yet another program) to have stored in my PC, clogging up, and taking up space. Thx in advance - g.
