Callback File Function is freezed for few second(3 - 6 seconds) frequently.

I tried to download and save file using Internet Explorer.
And It is not the problem related to Internet Explorer because other application
such like outlook.exe and chrome.exe... have the same problem.

Below is example logs.

Thank you for contacting us. Is the problem reproducible with the Mapper (or another) CBFS sample?
And, if possible, please collect logs with Process Monitor from sysinternals.com and give it to me. Set there a filter like "Path"->"begins with"->"X:", where "X:" is a drive letter for your CBFS virtual disk. Then reproduce the problem and save the log in the Process Monitor native format.

Thanks for your rapid response.

I Think I found the reason.
After turn off Kaspersky Realtime Protection, freezing is not occrred any more.
If freezing happen again, I will send Process Monitor Log.

Thank you again.
