AVS Definitions Update Seemingly Not Working

[jan714]

Have been a devoted Avast! user for two years and this is the first time this has happened.  Background:  WinXP, broadband connection. 

Noticed the little red warning message that the Avast! update did not work.  Right clicked on the spinning Avast! globe and chose UPDATING > !AVS UPDATE ... nothing happens. 

Rebooted machine.  After completion of reboot, Windows Security Alert box opens advising me my antivirus definitions may not be current.  I opened the Avast! Simple User Interface and tried executing the update from there ... no response.

Since this is the first evolution of this situation, I'm a bit stumped.   I have a valid registration and all other functions of Avast! (email guarding, etc.) seem to be working just fine.  Any help would be appreciated.

Hi,

  Have you tried repairing avast! installation?
        Add/Remove Programs>Avast! Antivirus>Change/Remove>Repair

Thanks for your reply.  Yes, I've already that which you suggest.  The result is an error message that states: 

     avast!
     A setiface error has occurred:  2
     Try to reinstall, or contact Support please.

Forgive the delay in responding, xmas.  Had a minor emergency to contend with before I could get back to this board. 

To answer your question, yes, I did reinstall it ... however, it's worth mentioning that I had to reinstall it it TWICE for the problem to vanish.  Seems to be working fine now.  Have a new computer coming any day now so I'll need to repeat the process all over again. 

Thanks for taking the time to respond to my query.
