hey everyone , i guess some from BD vendors know me or maybe all of them ! 
i just creates some of crypters that make the exe UD from AV's just for research , i found out that the BD has a nice heuristic scan but to be honest its not that hard to bypass ( small code make the exe file UD from BD's heuristic scan )
i am not saying that the BD is bad av its really one of best av around , well even when the BD detected the malware its easily to hexed and even when its become non possible to hex ( 85% can be hex :S )
the ****** kiddies always has the solutions by using UD exe crypter , the BD vendors are doin nice job to discover the new malwares but not that enough coz the spammers or the ****** kiddies will never use a public crypter or malware that detected by av's , i can see thousands of UD trojans/malwares/viruses releasing daily in the undergrounds forums !! , i just can say that the normal users are not safe anymore even if they got av install they need a strong clue about the malware/viruses world to become safe , i got alots of mails every day from spammers/****** kiddies to make thier exe UD and thats really make sick !!
I WANNA SAY THE BLACKHAT IS UP AND BECOME MORE DANGER DAILY AND THE COMPUTER'S SECURITY VENDORS ARE DOWN !!
just my 40 cent and sorry for bad english 
MY BEST WISHES TO BD
