Sandboxie causing "An anonymous session connected from [MY COMPUTER NAME] has attempted to open an LSA policy handle ..." on Windows 10

I'm having this exact same error but I'm using Win7 64-bit, Sandboxie v5.30.

All drivers and OS updates are current. I'm using Firefox and Waterfox.

Hi Sam.

Thank you for the update, I'm glad I'm not the only one. Never had such issues on Windows 7 myself, did you have them before installing v5.30?

With all that has been going on with Sandboxie in the last few months I prefer not see such errors which could be interpreted as some sort of Malware infection.

All,

I've shared the info with the devs.  I will update this thread once I receive a response.

Regards,

Thank you Barbara, very kind.

Hi all,

I was not able to repro the message on Win 10 1809 + FF 67, so it may be a combination of FF and certain AV software, or an extension. Try a new FF profile and a new Sandbox with default settings to see if the behavior continues. 

The devs stated that this is something on the program's end that not liking Sandboxie using Anonymous Logon (as nothing has changed with Sandboxie in that regard, and there is no malware in our code).

Here's an example of a similar situation:

You may want to reach out to Mozilla's support and see if they can verify the message and the steps. 

Thanks!

Hi Barbara.

This is what I tested today:

1. I created a new Firefox profile
2. I closed KIS 2019
3. I created a new Sandbox
4. I launched the browser in the new Sandbox and no event was logged

1. I rebooted
2. I launched the browser in the new Sandbox without closing KIS 2019
3. The event was logged

So the issue is not with my regular Firefox profile and/or my regular Sandbox.

It seems to be a conflict with KIS 2019(which I don't have installed on my other machines).

As this event is only logged once per day, I will try again tomorrow with KIS 2019 closed.

Thank you.
