I ran a Belarc Advisor

Question

I ran a Belarc Advisor test on my computer today. The score result was just 3.13 & fairly low. The Belarc Advisor performed a security audit of my system using the CIS Level-I benchmark appropriate to my operating system. The result is a number between zero and ten that gives a measure of the vulnerability of my system to potential threats. The higher the number the less vulnerable my system. Could you pleasetell me how can I go about increasing my score in future?
