Computer viruses—just the thought of your trusty PC catching one is probably enough to make you sick. Thanks to the cyber-sickies who persist in coming up with new strains, there’s a major new cyberattack nearly every day. Viruses sneak in, usually through e-mail.

Fortunately, there are ways to inoculate and protect your computer. Computer Viruses For Dummies helps you:

  • Understand the risks and analyze your PC’s current condition
  • Select, install, and configure antivirus software
  • Scan your computer and e-mail
  • Rid your computer of viruses it’s already caught
  • Update antivirus software and install security patches
  • Use firewalls and spyware blockers
  • Protect handheld PDAs from viruses
  • Adopt safe computing practices, especially with e-mail and when you’re surfing the Net

Written by Peter H. Gregory, coauthor of CISSP For Dummies and Security + For Dummies, Computer Viruses For Dummies goes beyond viruses to explain other nasty computer infections like Trojan horses, HiJackers, worms, phishing scams, spyware, and hoaxes. It also profiles major antivirus software to help you choose the best program(s) for your needs.

Remember, if you don’t protect your computer, not only do you risk having your computer infiltrated and your data contaminated, you risk unknowingly transmitting a virus, worm, or other foul computer germ to everybody in your address book!
