Which is the good proxy software which is free available?
Proxies are really not very good at all and they get blocked all the time as you probably know. Plus they have issues with many web site features that make them useless. The number of proxies run by hackers is also growing daily and you risk your computer and more using one that claims to be anonymous. Plus they are easy to break and leak information. The only proxy I’ve found to be somewhat useful because it changes IP’s daily is http://www.ippredator.com/index.html It is a limited proxy and only works with a few sites. But it seems to work most times and is safe to use. The better approach is the Personal VPN which unblocks everything, encrypts your entire connection for security, and doesn’t get blocked daily. Plus it works on all web sites and all applications including flash.
