Hi zahnartz62

I doubt that it’s a Windows update that has done it – My Win8 installation is set to update automatically and I have had no issues. There may be more than one exclusion setting needed in your AV; for example, scan exclusions and process exclusions. I use the included Windows Defender (which incorporates MSE in Win8 ) and nothing else since I don’t like to use more than one anti-virus, and have always found MSE adequate in Win7.

RoF would obviously work since you’re not using a modified launcher to run it. Have another look at your AV settings.
