RPC Error

I have installed avast! 4 Home and registered it with a license key. I keep getting following message when access protection control is activated - AAVM subsystem detected a RPC error.
Can somebody help please?
Thanks

i had the same problem and it seems that today i fixed it !!!

don’t know what is the “solution” but i can give you the steps i’ve done.

this is referred to Windows XP SP1
Install the following MS updates (maybe this is not importante but since i’ve done that…):
KB824146
KB833330

then open command prompt and type:
sfc /purgecache

then insert winxp sp1 cd into one of your cd-rom reader and in command prompt type:
sfc /scannow

wait for the process to finish (al least 60% must be done), reboot, et voilà…

this solved my problem, good luck!

I did not try the mak’s solution that seems good… But some RPC errors are corrected with a full uninstall / boot / install again.
Are your Windows RPC Service starting automatically?
