How to Remove Viruses and Spyware for Freeby eHow Contributor
Viruses are an unfortunate fact of information technology. Short of never connecting to the Internet, there is no way of completely avoiding exposure to viruses and spyware. A complete protection strategy is important to safeguard your system and data. Windows includes a firewall in the operating system as of XP. However, you'll need to install an antivirus program for complete protection and virus removal. Many excellent paid commercial applications are available to fill this need. However, several free antivirus programs exist to provide basic protection at no cost.
