Returnil Virtual System 2010 Home Lux will be less ideal for computers that undergo a lot of changes - for example, a PC that routinely has lots of different software installed on a regular basis. Even then, with proper management, Returnil can provide optimum protection for even the most non-static environments.
Returnil clones your installed operating system and runs that clone in virtual memory. When you shutdown the virtual machine, there's no trace left of your Web surfing and any malware that got onto the system will disappear when you reboot the PC. Of course, you need to ensure you setup the Returnil clone from a non-infected installation to begin with.
Returnil supports both the 32-bit and 64-bit versions of Windows XP, Vista, Server 2003, Server 2008, and Windows 7.
Returnil Virtual System 2010 Home Lux retails for about $40 USD, for a year's license on up to 3 computers. A free version with a limited feature set is also available. With the free version, however, you won't be able to access the hard disk from the virtual machine.
