I found the following in the FAQ sheet regarding
"Other questions".I installed the Microsoft Updates that the AutoUpdater downloaded for me to install and it fixed the problem!!!
---------------------------------------------------------------------
There´s a red circle on avast! a-ball icon in system tray and when I click on it, the error message appears saying "the AAVM subsystem detected a RPC error". How to fix this?
A: First, use Windows Update to be sure that the RPC service is up to date. Then restart your computer and check if the problem persists. If it persists, follow these instructions:
1. Right-click the icon MY COMPUTER and select MANAGE.
2. In left column unroll SERVICES AND APPLICATIONS.
3. Click on SERVICES.
4. In the right column, look at the state of services avast! Antivirus and Remote Procedure Call (RPC).
5. If any of these services isn´t set to start automatically, set it that way (right-click it and select PROPERTIES and the STARTUP TYPE set to AUTOMATIC).
6. Restart the computer.
This solution works on Windows NT, 2000, XP and 2003 only.
