Avast 5 sometimes protection is set off

Since I updated to the new version, the protection is sometimes set off, when I start my computer.
I don’t know why.
Of course its easy to start it, but I don’t know if my parents notice, when they use the computer and this is why I’m worried.
Does somebody have the same problem or solved it?
Thanks

it’s been reported several times recently…no official answer yet…pending ;D

Yeah… there are more and more users complaining of that…
Any acknowledgment of this would be good.
