If you've been on the Internet for any amount of time, you are likely aware of two obvious things. The first it that the Internet is a fantastic place that is filled with wonderful information regarding any topic you can dream up. The other is that just beneath the surface, there is an evil entity lurking that may very well cause damage and destruction to your expensive machine, and your data that didn't come easily over night. What I'm referring to, is spyware, adware and malicious software. Let's take them apart one by one, and figure out what to do with these sometimes horrid programs. The first is spyware. There are good kinds, and bad kinds of spyware. Of course, you likely can't think of any good ways to use spyware. Suppose that you are in charge of several workers who use computers all day long. You would lose money if they spent too much time goofing off, and didn't really spend time doing what they were supposed to be doing. So spyware in this case would simply be programs that are installed on all the machines that monitor your employees activities. This is natural, legal, and expected. The other good way to use spyware would be if you were a parent who was worried about your child visiting certain web sites, or using certain forums and message board where they may be exposed to unsafe elements or people. In this case it might indeed be very wise to use spyware to ensure that you child isn't wandering into one of the many precarious areas of the Internet. The kind of spyware you don't want, is probably the kind that you already have and don't know about. There many different intentions that spyware comes with. Some are completely harmless, and can even enhance your browsing experience by remembering certain elements whenever you visit your favorite web page. This is helpful as it allows your browser to load the same pages with the same information much quicker each time you visit the same site. Many others, are there not to help, but to do harm. They are there to create revenue, in form of advertising, for their creator. This is where spyware and adware work hand in hand, and many times are the same program. Suppose some kind of software creator who is just starting out wants to give away some free software. He then learns that by including a spyware/adware combination with this free software, every time somebody clicks on a pop up ad, he gets paid. It seems harmless enough. The problem comes when you have so many of these programs on your computer that it slows down to a virtual crawl. This is when you need to do something about it. The next step toward the dark side of evilness is malicious software. These programs are designed to do nothing worm their way around the Internet and cause as much destruction as possible. Naturally the best way is to find a robust and hearty program that will not only get rid of the junk you've likely already got, but keep new stuff from sneaking as well. These will rapidly, simply and over and over again find and get rid of software that shouldn't be there, and keep your computer safe in the future.
