Updates - Pkg. is broken??

[veegee]

Could someone help please.
The popup update alert from Avast says:  An error has occurred while attempting to update.  When I click on 'more info', it says:  The package is broken.  Total time:  6 s
I tried a manual update, it reports 'package broken' also.  Please explain what is wrong here and what can I do to fix it.    This just started today.    Log below, mentions something about 'old version' and deleted registry and running setup???  Am still using  Avast free 4.8  and have not upgraded to version 5 free yet.
Thanks in advance.

ry a repair of avast. Add Remove programs, select 'avast! Anti-Virus,' click the Change/Remove button and scroll down to Repair, click next and follow.

Thank you DavidR for your reply. 
But, have to say that the next morning when I started up the computer, updating of Avast was working as usual, and I didn't have to do the add/remove thing.   
Sorry to have bothered you.

[DavidR]

No problem, the main thing is it is working as it should.
