Daily error message

At least once a day, I get a notification message from Avast Security that there was an “internal error” and I should check the system log. The only thing I see in the system log that appears to be relevant is:

I don’t know what’s going on. Maybe someone else does? In any case, this appears to be a daily occurrence and the information in the log appears to be the same each time.

Hello,
please run Console application (cmd+space, type console + enter), select System Reports on the left and check whether there are any crashes of processes called com.avast.service. If yes, send me a few please on ondrej dot kolacek at avast dot com.
Also what is the version of AV?
Kind regards,
Ondrej Kolacek
