Malicious software (also called malware) is any software program that’s intentionally designed to cause your computer harm or invade your privacy. These are not programs you purchase, or programs from reputable software manufacturers such as Microsoft, Adobe, Apple, and others. They generally don’t have icons, and you don’t have to run them yourself. Rather, they’re tiny programs that are hidden inside your system and do their dirty work without your knowing it.

As you learn in this chapter, several forms of malware exist including viruses, worms, spyware, and adware. As you also discover in this chapter, you can take actions to prevent your computer from getting malware. And when it’s too late for that, you can take steps to get rid of malware. This chapter starts with a discussion of the most prevalent form of malware today, spyware.
