Windows

If you're using Microsoft Windows, here are a few recommended steps to take immediately upon reading this, if you have not already done so.

1. Install a Firewall. This will close all your ports from being accessible from the public internet.
2. Install antivirus software. Make sure you are getting the latest virus definitions (information about the latest viruses) with your configuration. This is important, as new viruses are released daily.
3. In internet explorer update your computer by scanning your computer and installing high-priority/recommended updates.
4. Install another browser like Mozilla Firefox or Opera as Internet Explorer has a long history of security incidents.
