Unrecognized files time takes to be decided

This has probably been asked before but I can’t seem to find a definitive answer on average how long does it take for a unrecognized file to be analysed? The reason I asked this because Comodo has put Tweetdeck into unrecognized and as it is not hurting the way in which the program runs I have left it there to see when it moves. I have now been waiting over a week since I have come back to Comodo and would of thought it would of moved by now out of unrecognized and specially as Tweetdeck is so widely used.

Just wondering if anyone had the answer
