after installing office 2003 it seems that avast home has problems starting: just after the boot of the system the avast icon show a red mark and is stopped. if I double click on the icon I get the following error:
"the aavm subsystem detected an rpc error, the operation could not be completed"
then after waiting some time the red mark on the icon disappears, and avast seems to work properly, however i'm not so sure that it's working correctly.
