Many BIOS versions offer partial virus protection of the Master Boot Sector. This creates problems when an access control product is installed that is designed to encrypt the master boot sector (the partition table is created). The computer's BIOS prohibits any writing to the Master Boot Sector, and so prevents the encryption process. If you know you are using this BIOS function, you must remember to disable it before installing an access control product.
If the above options do not provide enough security for you, download Access manager for Windows.
Access manager provides much more security than standard ways in Windows.
