Common Computer Virus Questions and Security Tips

  • What is a computer virus?
    Think of this as a biological virus, like the flu. It keeps you from functioning and often needs something powerful to get rid of it. Computer Viruses infect your programs and files, alter the way your computer operates, or stops it from working altogether. It's estimated that the Conficker virus infected more that 10 million computers in 2009. Tens of thousands of computer viruses now operate over the Internet, and new computer viruses are created and discovered every day.
  • How does one find me?
      Simply being careful isn't enough. You can pick up computer viruses through normal Web activities like:
    • Sharing music, files, or photos with others.
    • Visiting an infected website.
    • Downloading free games, toolbars, media players and other system utilities.
    • Installing mainstream software applications without fully reading license agreements.
