False positives droped a bit or...

I have been scanning some folders with some keygens, cracks etc. and I always had about 7-8 detected by Comodo.
In the last hour or two, Comodo updated and now I have only 3.

Is it a bug, or just some false positives get on the white list?

Correction, my mistake.
I seemed to move some folders from my designated scanning area.
