Unlike you, I have had RPCSS.exe access the net, and also receive, regularly…
Why should my RPCSS.exe be wanting access to the net, and not yours?

pcb,
I wish I had an answer for you, but my rpcss does not communicate with the internet. I have never heard of Ignite, but that may be a service in Europe that does not extend itself to the US.
Hopefully, VLK who is the senior guru might come back with some more information.

Fact remains, if you disable rpcss completely, Avast will not do anything!

If we keep “asking”…we may get a more detailed answer from the Avast Team.

Wish I had more to offer on this, but I am as puzzled as you.
