Hi Soot,

Please could you confirm that the communication with the Lightstreamer server in not secure?

However, if an antivirus software intercepts the data flow and randomly modifies messages before your client receives them, it is something we can not avoid.
What is strange is that such behavior should impact other services and not just Lightstreamer.
Our communication protocol is completely agnostic on the representation of data, which interpretation is completely free between the Data Adapter and the client.
Furthermore a randomic modification of our message with very high probability should break the simple communication protocol, and make the message unrecognizable by the client.
Only have a scale error on prices is something the puzzled me a lot. But to investigate this we should have a pre and post antivir flow capture.

Regards,
Giuseppe
