Finally , Zemana reply my email .
And not surprisingly , i asking about more information for ZAU , and they still response :
At present, we are unable to commit release date.
And also i had ask other question about why Zemana stop update there product for pretty long time ,
and they reply :
It is quite stable now but we will release an new update on next month.
For myself , i agree Zemana it's quite stable now ,
but indeed i can feel Zemana Malware detection capability seems worse than before
I had using some Malware samples (which collect from China、more than hundred files) ,
to test HitmanPro and Zemana many times already ,
and the result usually are very close .
But seems from 2017-May or maybe earlier ,
i can feel Zemana detection performance start worse than HitmanPro !
And also Zemana refuse to talk about what engines they using ,
so we can't know what is going on .....
this quite make me feel bad
But at least , every time i test those samples , Zemana scan speed still pretty good ,
and always faster than HitmanPro , this should be praise
