I won't type the long form all the time... I know that... B e h a v i o r  S h i e l d...
We'll go for an abbreviation. Better if it is officially taken by avast team, the father of the child

Sorry Tech but I have to agree with marc-d-l
Abbreviations only add to confusion.

You can please some of the people all of the time and all of the people some of the time but you can't please all of the people all of the time?

Why is abbreviation such a big word

Well we can always do what should be done, use the long form followed by the bracketed abbreviation in the first use and use that afterwards, Behaviour Shield (BhavS) or (BSh) or (BhvS), etc. etc. whichever you are using.

Which is perfectly acceptable since the guess work has then been eliminated in the post or reply if always following that rule.
In that case, even BS is an acceptable abbreviation
