You released a new version. Should I update, and how?
YES! You should periodically check for and update to the latest version using the program’s update function to stay current with the latest methodology in preventing current malware.
This process is entirely automatic for users with a purchased license (which includes automatic updating functionality) however the free edition available in older versions of the product can only update to CryptoPrevent v9.1, the last version in which the free edition was available.
After update it is then necessary to re-apply the protection to your system. It is not necessary to undo the previous protection in place before doing this, or even to uninstall the app before updating.
