Can you reboot and try again.

[mrapi]

it is happening for couple days,I got error on every first boot of the day

[Boggin]

Can you try an uninstall/reinstall of the program to see if that resolves, but if you have Windows Repair installed, it has a registry back up option which utilises the same back up program you could try to see if that gives the same error.

Have you installed anything within the last couple of days that coincided with this error ?

If that doesn't apply and the error continues, I'll pass this on to my Support to have a look at.

I think the problem occurred after avast updated to newest version...

[Boggin]

Do you have a restore point you can use to before Avast updated to confirm ?

[mrapi]

I don't have, but surely that is the problem

[Boggin]

To confirm then, try the backup in Safe Mode where Avast won't be loaded, but neither will a number of other services, but as it's the only recent change then that may confirm Avast as being the culprit.

I don't know what to suggest for that other than to either uninstall Avast or contact Avast to see if they can whitelist the program, if it is the program it is interfering with and not the other files.
