Virus definitions

I turned my computer on today and everythings ok,avast updated the definitions right after I turned it on,but then I got a message saying my virus definitions were out of date and I needed to update them,which I did. But whats strange is I have the virus definitions set to automatic update,so I don’t know why I would get that message.

Latest VPS version is 20150506-3
If you have that, don’t worry.
If not, try a manual update and see if it is working.
If not, perform a repair of avast.

I checked and I have that version Eddy,thanks,I’ll keep an eye on it though for anymore problems.
