Software to protect your computer

As always, make sure your Windows system is up to date!

My suggestion for Windows users is Microsoft Security Essentials. I have used AVG anti-virus, free edition in the past so feel free to check it out (but MSE is my first choice) also look at as is Avira.

For firewall protection, my personal opinion is if you are semi-smart about your web surfing habits then they built in firewalls for Windows XP or higher is good enough. If you feel that you need something more then look at either Comodo (which also includes an anti-virus program) or Webroot firewall

For anti-spyware, see Microsoft's Security Essentials above, Spybot Search and Destroy, and Malwarebytesare good choices.

Finally, make sure your software is up to date by using Secunia's on-line scanner. You can also download a version to run locally on your computer.
