Features
The program primarily is the feature. Most features are hidden from the end user. These features are the high tech engine that checks and maintains files during the post BIOS / pre operating system loading.
Performance and Testing
The system was tested on Windows XP Professional inside of VirtualBox. This testing is as real world as it gets considering virtualization is one fastest growing forms of information technology. The boot is delayed of course due to Persystent's check of your operating system. This is expected and well worth the wait if you are protecting an operating system. After loading Windows XP, and deleting several files from the operating system, I rebooted only to find my system still funtional. Users are allowed to interact with Persystent and any interaction is simple and easy to use.
Viruses and Malware
I deliberately installed a virus on the test computer (Virtual computer running Windows XP Pro) and again, Persystent Repair again delivered as promise and corrected the system files that were infected. Persystent Repair is perfect for any user.
