Instead of paying for AppGuard to prevent theft of private data by restricting read access to it, why not use freeware Truecrypt plus Shadow Defender (which I have a license for already and is highly recommended to everyone). Malware can then read but not decrypt the data that you have in a truecrypt container. To access the data, you reboot with shadow mode disabled, mount the data, modify, unmount, and reboot with Shadow Mode enabled. How is this as an alternative to AppGuard? More secure? Any additional freeware strategies?
