I recently downloaded a software, HideIP Platinum, because one of my friends told me it was great. It's a software that hides your IP address to help blocking spam. If you were banned from a forum, this software will allow you to create a new account on this forum. If you have already voted for something on a website, this program helps voting almost indefinitly. You can also see in wich country you "are" (that's your proxy). Then, advertiser think that you are korean, chinese, american, etc..., but it's flase. Plus, the software automatically connects to the faster proxy available. That means that your Internet connection speed is not really affected. It supports both Mozilla Firefox and Internet Explorer, so you can easily switch between anonymous surfing and normal surfing, just by pressing CTRL+W. You can test it for free for 3 days, but I stongly recommend you to buy it!!!
