It has the ability to replicate itself and thus it quickly spreads all over the computer damaging all important files and data. It is designed in such a sophisticated manner with complicated multi-layered coding that it becomes impossible for a normal antivirus program to detect its existence in the system. It lingers into the system in disguised and encrypted format. Gradually, it depletes the important files and programs in the PC, ultimately making the PC perform extremely slowly and sometimes even it crashes out.
