Anti-virus software protects your computer from viruses, spyware, and other malicious software. It works by looking for patterns of known worms and viruses in files you download and programs that are running on your computer.

Since the virus writers are always creating new worms and viruses, your virus protection software needs to be regularly updated to recognize the latest threats.

Many computers come with anti-virus software pre-installed. When switching anti-virus programs begin by uninstalling other anti-virus programs that may be installed on your computer.
