I am looking for a security program that will be easy for me to install myself and will make it easy for me to keep track of any issues my computer may have. I have heard a little bit about the Retina Network Security Scanner, and it seems like it fits all of my needs. Where do I find one of these security scanners? Is this something that I download off of the internet? I really like the idea of having a program that will locate the problem and fix it by itself. This would save me so much time.
