There are many antivirus/antispyware products to choose from. Some cost money and others don't. The problem is trying to find one that works and doesn't slow down your computer. In my search for a good a product that can get the job done but doesn't cost a penny, I've found a great product that I currently use and that I highly recommend:
COMODO Antivirus
