rpc error

hi,
it take more than an hour to boot on …
when i click on the icon of avast(right corner) i get a pop up :
The AAVM subsystem detected an RPC error.

hoiw can i solve this ?

best regards

Both avast services must be running automatically at windows startup.
Generally, RPC errors are corrected by Control Panel > Add/Remove applications > avast > repair function.
If this does not work, try uninstall/boot/install/boot.
