For those people who don't want to install potential Malware on their computers.
I suggest they look at created a Virtual Machine (VM).
The software i use is called "Virtual Box" which is currently Open Source.
http://www.filehippo.com/download_virtualbox/You will need to create your own virtual OS (or download an existing one).
Once you have one, you can install as much crap onto, then delete it and reload from backups =)
Also, for those outside the US/UK do a Google search for open proxies and install them on your browsers,
this will make the system think you're in the US or UK allowing you to get more free offers.
