Current estimates say that somewhere between 65 percent and 80 percent of all e-mail on the Internet is spam. With those kinds of numbers, you can easily see where the doomsday predictions are coming from, but the fatalists are ignoring an important fact, which is that where there are problems, ingenious people are always ready to solve those problems — usually for a fee. Spam filtering has progressed a lot from the early days when it was looking for certain “bad” words and filtering out anything with any form of any word in the list. Modern spam filters can examine word usage in context, recognize patterns in e-mail that look spamlike, and dispose of 97 percent to 99 percent of actual spam. Although the same kind of useful statistics aren’t readily available for spyware as we write this book, a lot of people are taking notice of spyware’s impact on Internet computing. Huge, faceless corporations are tracking everyone’s personal Web-surfing habits through tracking cookies, scumware is replacing banner ads on Web sites, and key loggers are recording online banking and other management of sensitive corporate and personal information.
