I forgot to set my external harddisk as exclusions. When I just installed a software, then I open the crack folder. BitDefender just directly delete my crack file. I have no choice to turn off the real time protection and download the whole software+crack again!
One more thing, BitDefender is more ######! Kaspersky is better than BitDefender, BitDefender is don't care what kind of game trainers or game hack programs. It just consider the file as virus but Kaspersky will not. Thats why BitDefender so ######!
