24th Century Enterprises Recommends:

If your computer is full of Virus' and or Spyware or just running slow for no good reason and you would like to clean it up yourself. Try these tools available free from the Internet. If you learn how to use these you will definitely keep your computer and Internet Explorer cleaner and faster and save yourself some money.

Spybot Search & Destroy™
Spybot-Search & Destroy can detect and remove spyware of different kinds from your computer. More and more spyware is emerging that is silently tracking your surfing behaviour to create a marketing profile of you that will be sold to advertisement companies. Spybot-S&D is free, so there's no harm in trying to see if something snooped into your computer, too :)

SpywareBlaster™
Prevent spyware from installing in the first place! SpywareBlaster can help keep your system spyware-free and secure, without interfering with the "good side" of the web. And unlike other programs, SpywareBlaster does not remain running in the background.

AVG Free 9.0™
I highly recommend this one!
AVG Free Edition is the well-known anti-virus protection tool. AVG Free is available free-of-charge to home users for the life of the product! Rapid virus database updates are available for the lifetime of the product, thereby providing the high-level of detection capability that millions of users around the world trust to protect their computers. AVG Free is easy-to-use and will not slow your system down (low system resource requirements).

ClamXav (for MAC's)
To be fair to those of you who have decided to go the way of Apple. This is a Free Antivirus Software available for MAC users, Link will direct you to the download page, and you must select according to which version of MAC you are running. Since I don't use MAC anymore I can't give any review on this product, But others have reviewed it as being equal to other anti-virus available and the only one out there that is FREE.
