You don't have to install GhostVolt Start, just download and go for it. What does that mean? You can take it anywhere you go and secure data on any other windows machine: the home office, your laptop... hey, even put it on a flash drive and use it on the go.
Data encryption completely obscures your personal information, rendering it completely useless to any invasive attacker. Even if you aren't targeted and loose your laptop your encrypted data is always hidden.
