This version is different from here on out. There will now be a "Paid" version of Hosts Block.
The chart below will show the differences.
The cost per license is $5USD. I've thought long on this because I've spend money on the encryption DLL that does a lot more than just encryption. License are lifetime of updates, and Hardware bond to the PC.
The Feature "View changes in hosts file", The lets you see what has been add, and removed at each update. That is if anything has changed to the host file. Now Active Protection uses this too. In Silent mode(Auto) and Alerting will show you what has been found with dates and times.
