Question: Tofind out if my computer already has anti-virus What steps should i take? 

Answer: Assuming you run a Windows PC: Double click "My computer." Find and click "Control Panel." Click "Add/Remove Programs." Allow your pointer to rest on the name of any program on your list and windows will give you a brief description of what the program does. Common pre-installed anti-virus programs are "Norton" and "MacAfee."
