Red box

I keep getting a red box come up saying that i am using an old version which needs updating, windows also tells me that the anti virus is out of date. I have updated it though and am using 4.8

Is the system clock set correctly? (especially the “year” value)

If that does not help, please, post the last 200-250 lines of avast log: C:\Program Files\Alwil Software\Avast4\DATA\log\Setup.log

Is the manual update working for you?

Is the update working when your using avast 4.7?

Thanks to all. The date was incorrectly set! which seems to have resolved the problem
