Please a need to know the windows services that avast use. This is important!
Joel, as you can see from my posting:
http://www.avast.com/forum/index.php?board=2;action=display;threadid=651
…I am querying the Avast team about RPCSS.exe, which is one of the Windows services Avast appears to call up.
You seem to be having an error caused by this application- RPC is RPCSS.exe I presume. Is it actually in your system?
The moderators do not appear to be interested in answering our queries…I wonder why ?

You guys need to calm down a bit.
The moderators will answer your questions as will other more experienced users. It takes some time to review all the postings on the forum, and then research them to provide a proper answer.
Please be patient. 
Thanks
