Hello Ramesh,

I tried it before, it doesnt help. See the photo how it seems - https://ibb.co/w649yFH

And also there are the logs which I said when what is it doing when it stutters - https://ibb.co/4S7sxxT

Thanks for answer tho.

H isebix0_,

The ProcMon log shows the subfolders of the Steam folder are being scanned by Defender. Have you tried adding that folder to the exclusions?

Please share the screenshot of the exclusions list in Windows Security.

Also, share the zipped PML log if possible.

Hello Ramesh,

I only tried to add in the Exclusion list:

MsMpEng.exe (which is the Antimalware service executable)

Forza Horizon 4 folder (i didnt tried to add the subfolder where the Defender is scanning tho, just the whole game folder)

And the Windows Defender folder

• I sadly cant share the log file as I checked that few days ago and didnt saved that. But its still the same as it was.

Thanks for answer again.

Hi,

Have you run a ProcMon trace after adding that folder to the exclusions? That's the only way to find if the exclusions are working and to know if Defender is scanning some other folder/file. Please run a new trace and share the zipped log.
