Returnil
Returnil, as the name suggests, doesn’t let anything affect the main drive where Windows is installed, namely, c:\. It archives this through virtualization technology, creating an abstract layer over the main drive. This means that any changes made will automatically be saved for only the current virtual session, and will be automatically erased upon reboot.
This technique can easily thwart viruses and malicious spyware programs as any changes made to the system are simply reset when you restart the system. This is also perfect if you want to test software. However, you need to be extra cautious as to where you save data. If you save personal files on the C drive after the protection is activated, say goodbye to it the next time you reboot. The software is great as an added layer of protection, but is easy to forget about (in spite of a bar runs constantly at the top of your screen) in daily use. The program uses hardly 25 MB for the virtualization process which is incredible, and is simple enough for even inexperienced users.
For: Resets any changes made to the system, so no spyware, viruses etc.
Against: Needs to restart for protection.
