Most people are unaware of the vast numbers of files that are stored on your hard drive each time you browse the internet. Most of these files are just useless space hogs, but some are unwanted privacy invaders. Every site you visit will install "cookies" on your hard drive so that you may interact with that site, and these cookies are harmless. Unfortunately, some website cookies want to know everything you are doing on the internet, what sites you visit, what pictures you look at or download, detailed information about your computer, etc. and they sit there silently sending that data to the website, performing their evil deeds for years to come. They are capable of bypassing all of your protection programs. If you would like to eliminate these useless privacy invading pests, download these two free programs. They have been around for years and have been downloaded by tens of thousands of people (their safe and virus free). GO TO: www.download.com

Enter this name into the search bar and download it. You will be amazed at the amount of useless data these two programs locate and erase.
