If you use a PC, especially with Microsoft Windows, and you do not have an antivirus program, GET ONE. It's easy, and will save you much pain. Malicious software such as computer viruses, worms, and malware can slow or permanently crash your system, steal your personal data, send bad things to everyone in your email address book, use your computer for illegal activities by third parties... the list goes on. Make your life easier; get antivirus software and update it often.
