Softwares (Internet)

If you use Google AdSense, you will know that it is forbidden to click on your own ads. Unfortunately there is always a risk that you accidentally click on them, and the risk isn't limited to you clicking, anyone using the same IP number as you (such as your family members or office co-workers) could be clicking on them, especially as they may not be as careful as you are (or they may not even be aware of it). Google has no way of knowing who is doing the clicking and will assume that any click from your IP number is probably from you and decide to ban you from AdSense.
The AdSense Click Protection script blocks click events within Google's AdSense code and replaces it with a clean redirect to the advertiser's URL. This should (we hope) make it safe to click on those links. As a result the other parts of the ad block are not clickable at all.
