There is certainly lots of freeware out there on the Web for you to download. You need to be careful, however-- some of it is very good, some not so good, while some are annoying or even downright dangerous. It's best to download freeware from sites you can trust, like the sources I list below. And remember, you should always SAVE a file you are downloading rather than INSTALL it-- then SCAN it with your Internet Security software before clicking INSTALL, regardless of its source.
