I was wondering if there is a program that gets ride of a virus and protects the computer from further viruses? Also how do you find a virus that you have?

Yes, There are numerous anti-virus programs available.
One I would recommend is AVG Free - Download AVG Anti-Virus Free Edition for Windows XP and Vista (http://free.avg.com/download-avg-anti-virus-free-edition)

The free version of AVG is good but check out how it comares with other versions of AVG at:
