There are a lot of great free programs out there, but some of these downloads come with a catch – many fold in extra features or even additional programs. If you're not careful, you'll end up with a new toolbar or a weird program that you never asked for! The trick is to monitor the install process carefully. Most of the time, there’s a sneaky little checkbox – already checked – that represents your permission to download. You have to carefully uncheck those boxes to avoid unwanted stowaways.
Unchecky is a free Windows program that can help you avoid all of that boring fine print. Unchecky automatically unchecks all of the extra add-ons you see in the install windows. The program also warns you if you are about to install a potentially harmful or unwanted program. This makes it easier to keep your computer secure and free of such things. Unchecky also updates programs automatically, so you don't have to constantly monitor your programs. Just install once and you're done!
