Windows security centre

Just updated home addition with 4.8.1351 but my windows security centre is stating that this is an old version. Why does windows security not recognise the latest edition?

Welcome seh567

Check the system date and time very carefully as this has to be accurate.

Thankyou Yokenny

For some reason my system date was 2nd October instead of Sept. Revised and now Avast is showing in security centre so everything is fine and dandy again. Thanks
