JusMe,

I have in fact a couple of process viewers…started using them when I discovered RPCSS.exe in my TaskKiller list -wanted to find out about it.

And yes, I too have killed RPC on several occasions, without any apparent effect on Avast, but I wasn’t sure if it was effecting it’s ability to do it’s job properly.
You say that

NOT ONE PART OF RPCSS IS USED FOR UPDATING (we all know that now) OR KEEPING THE PROGRAM FUNCTIONAL

…but if Avast needs the service to communicate between it’s modules, won’t killing it prevent this “communication”?

Raman doesn’t seem too keen on your dll renaming trick. I expect it’s fine to do it, but I’m afraid I’m still not 100% convinced.
I think I’ll wait for more opinions, with respect.

all the best,
PcB
