Unfortunately, this easy way for people to exchange information is also an easy way for computers to exchange data â data with the potential for wreaking havoc on your life.When you open your computer to the viral payloads and destructive worms that can be carried by e-mail messages, you risk losing your productivity, your personal data, your financial well being, and possibly even your job.
