• Keep Windows (and your other Microsoft software) up to date!
  I cannot stress how important this is enough. Often holes are found in Internet Explorer or Windows itself that require patching. Sometimes these holeswill allow an attacker unrestricted access to your computer.
  Therefore, please, visit the Microsoft Update Website and follow the on screen instructions to setup Microsoft Update. Also follow the instructions to update your system. Please REBOOT and repeat this process until there are no more updates to install!!
  
• Keep your other software up to date as well
  Software does not need to be made by Microsoft to be insecure. You can use the Secunia Online Software occasionally to help you check for out of date software on yourmachine.
  
• Stay up to date!
  The MOST IMPORTANT part of any security setup is keeping the software up to date. Malware writers release new variantsevery single day. If your software updates don't keep up, then the malware will always be one step ahead. Not a good thing .
