COMODO Internet Security Premium - Unrecognized Files

As I mentioned in another thread, I'm new to COMODO Internet Security Premium which is the free version. I have it on an old computer (AMD Athlon
2800+ 1,81 GHz with 1 GB RAM) that I don't use every day but am too lazy to carry to the ... ... Recycle Bin.

I run it "out of the box - no changed settings" and it seems to me like CIS does a good job.

Updates are managed in the background with the "widget" changing colour from red or orange to green. Today, after downloading the new database, it offered to automatically update itself from 8.0.0.4344 to 8.1.0.4426. It was smooth and after a restart, it worked fine.

It seems light on the resources. During the first few runs, I wanted to see what happened in Windows Taskmanager as well as in COMODO Taskmanager but as soon as I touched the mouse or keyboard, COMODO paused its tasks and I saw nothing.

My only issue is about "Unrecognized Files ". When I updated Java, three files appeared, were submitted and are "waiting for classification" since mid january. How long does it take CIS to clear those files?
