Turn off unnecessary processes
There are alot of programs that run in the background of your computer and some of those programs open up ports that can allow a hacker into your computer. By shutting down these programs that are most of the time unnecessary we can eliminate the amount of ports we have open on a computer.

You can also purchase a third party firewall program that will help block these ports. There are many third party companies that provide excellent firewall programs. Firewall Gold
Have a router between you and the internet
Some ISP (internet service providers) such as cable allow you to plug into their modem and it gives your computer a public IP address. By installing a router between your ISP modem and your computer you can not only share your internet connection but you are also protecting yourself by not publishing your IP address to the internet. A simple router is pretty inexpensive depending on the features that you get with it like wireless. Places like Best Buy and Global Computers have these routers.

One of the most common ways computers get viruses and malware is from software downloaded off of the internet. Certain programs downloaded from unknown sources contain viruses embedded within the program. The best way to protect yourself against this is to not download software unless it is from a site that is totally trusted.
By following these eight steps you can significantly decrease your risk at being hacked or infected by a virus. The most important thing is to use common sense and you will stay protected.
