I’m wondering what OA is doing connecting to this IP address if you were just running a converter program, there shouldn’t be any need to connect. Interestingly for that IP address, MBAM Pro would also block it. So I have no idea why OA UI would be trying to connect to it.

So I suspect this alert on your system or rather OA is unrelated to the actual converter program.

When posting screenshots a) crop them to only show what is relevant and b) use the .gif file format which is generally a smaller file size.
