The first thing to get is a good free ant-virus program. I like these listed here. among others. I trust these.
As far as free Anti virus programs go, these are some of the best ones that I have used. http://www.avast.com/index.html I like this one, just because it is easy to use and is fairly fast. It’s really important to protect your computer with Anti Virus. Get AVG Free http://free.avg.com/us-en/homepage. So you mine as well do it for Free! I do and I like it!
I use Avast on my own computer.
