1. Install all windows critical updates for your operating system from the Microsoft Update site – it’s free! All that’s required to keep your Microsoft operating system up to date is an Internet connection.
2. Install and configure a firewall – either a hardware or software based firewall is a must! If you are using a router, it probably has firewall capabilities included. Software firewalls are available at minimal cost; one of the best is free!
3. Install and configure antivirus software – the cost is minimal, there are even free versions available – the protection is priceless! Update the definition files daily – scan your drive weekly – it can all be automated with most programs.
4. Create a backup – even the best plan can be circumvented – be prepared for the worst with a complete backup of your hard drive! If you already have a CD burner and software installed in your machine, you probably have the tools to create a complete system backup – for only the cost of a few CD-R’s!

Obviously, the costs to properly protect yourself from the worst threats to your security are almost nil. If you need help with any step above, simply use a Google search to find help – it’s freely available.

Follow these four simple steps and you will have implemented comprehensive and complete protection for your PC.
