Hey there I posted on another post but received no reply whether the issue is being looked into,
Avast on Mavericks seems to be having issue
- initial error occur after mavericks finish installing( could not access preference pane)
- fix preference access via accessing incompatible software folder and opening it. (However there are two preference pane now in system preference)
3.com.avast.helper is it constantly running? its not visible so shouldn’t app nap be enabled? - & web rep seems to auto install by itself eventho previous set up before upgrading mavericks for web rep was not installed.
p.s: running avast on latest build
please do look into this issue especially memory/cpu usage of avast on mavericks
