They remove duplicate signatures from their Bitdefender engine!

EMSISOFT isn't the only one doing this kind of things. This happens with every vendor.

You have the explanation here (you can find it on other places like kaspersky FAQ): http://forum.bitdefender.com/index.php?s=&showtopic=53239&view=findpost&p=213563

What you are seeing is called "optimization." Emsisoft does it on a frequent basis to reduce resource usage and update times.

Other AV vendors do this as well.

Same as others here explained...

Another term will be 'spring cleaning'/ 'spring clean' which its normal for those AV products to conduct in order to make the performance to be optimize. Sometimes very old detection like for a decade needs to remove prior on many criteria like not sufficient to be exist for infection.

A very little amount should not totally affect its detection capabilities.
