Why does Pub Hack have False Positives?

Hey Dave i am just wondering why does the hack have to have flase positives wouldn't it be much easier if you could take them out it would be highly appreciated if you guys could take them out. Because i really hate having trouble with my AV and most combat arms hacks don't even show a positive in it. I am just wondering why are they there and what are they used for and why can't we remove them. Thanks

Dave uses Themida so that other people won't take credit for his work. However, Arun told me this and hes almost NEVER right. =D

So if hes wrong then why are they there. Also how can someone take his work if the message on the left bottom corner is coded into the hack? Well thanks guys!
