If you don't have an antivirus program on your computer Avast is a fairly good one. There is also MSE for Vista, Win7, Win8, and Win10.  We see very few issues with these AV programs and the Twitch App.

  • Run and update your antivirus definitions.
  • Do a deep scan (not a fast or simple depending on the AV) this can take up to an hour or so.
  • Once it has finished have it remove any remaining malicious files.
  • Reboot again


  • Check your OS for any updates and update any that may be there.
  • Check your Java and Flash this site should tell you if you are up to date with your Java and Flash.
  • Check your browsers and any browser addons/extensions for updates.
  • Reboot following any install.
