PepiMK,

The concept of being able to chose by registry tweak or other method between the two modes (less memory use, slower TT scan/More memory use, faster TT scan) at least enables TT to be optimised for the type of PC it is being used on.

I am less enthusiastic about the balloon notification. Sure, those who like to watch utilities work and who try to understand what the software is doing may like it. There is however arguably more users who simply want what ever protection software they install to do its job as unobtrusively as possible. They don't have the time or inclination to worry about how the protection works and they don't want it to interrupt them unless it is for something critical. They expect it to get on with its task and leave them to get on with theirs (what ever they are using the computer for). Of a group of 6 people I provide support to, 5 fall into this catagory, they are computer users, not enthusiasts. Perhaps you would consider also making the balloon a diagnostic option that can be turned on or off.
