Hey Allan, Thanks for your Response,


Unfortunately, It didnt Work. i Did Uninstall Flash the Second i Heared about the Malware.

i dont Have Any Programs Like VPNs or Cleaning or Anti-Virus Programms.

Its Not About the Connection, Its About Video Player in Safari That Freezes

I Did Clean my Mac Like a Week Ago after i got it Back from the Apple Store,


If you Find Any Solution, Please Let me Know.
