why my infinityMu window will automatically disappear ... what should i do? pls help me . is there anything i can download to fix the window without automatically disappear??
Have you tried adding an exception list at your anti-virus? More info here (Trojan problems), here (add an exception list), and here (client solutions)
Make sure that you must always open InfinityMU with administrator rights (Right Click Autoupdate/Main> Run as Administrator) cause I tested that if I don't open my launcher with no administrator rights, Mu will not open.
You don't have antivirus but you got Deep Freeze, First virus can bypass deepfreeze, You need to install antivirus on your PC to fix your problem, and I am sure that your PC got virus after you install some anti virus and the virus didn't remove you need to reformat your PC.
As I know your PC is virused ( did you tried to use something illegal " I mean SH/ AP" )
I would like to suggest you to didn't use anti virus to clean your pc try to clean your PC with http://ru.iobit.com/advancedsystemcareper/
