What is Malware?
Malware is an abbreviated term used to describe a "malicious software" program. Malware includes things like spyware or adware programs, such as tracking cookies, which are used to monitor your surfing habits. It also includes more sinister items, such as keyloggers, Trojan horses, worms, and viruses.
