help - rpc error - what is it

??? help me please - my antivirus software has encountered a problem. The little icon in the bottom right hand corner has a no entry sign thing on it and when i try to click on OAPC it says the AAVM subsystem detected a RPC error. Can anyone tell what it is and how to fix it??? please please please

You can just make a clean install again: I mean, uninstall, boot, install and boot again… This correct the majority of the RPC errors.

Another way is going to Administrative Tools > Services and configure both of avast! services to run automatically at windows startup. Maybe it will be easier to test this second way before the first one ;D
