Started a few days ago one program wouldn't open but everything else was fine. I ran malware bytes and it got rid of some stuff. I also have Norton Antivirus running all the time. Then a few days later I tried running skype and it wouldnt open either. It does open in the task manager as many times as I try to open it but the program never actually runs. Google chrome and Firefox are still opening just fine. But now if i try to open norton it crashes (aka not responding) as does VLC or windows media player if I try to play a movie. I have run malware bytes multiple times including in safe mode and it hasn't found anything. Please help.
