Windows security waring msg

[James jL]

Hi to all, i have a Windows xp security msg (in bubble from taskbar) saying:-
                                                                                                                          avast! antivirus 4.7.942 [vps 000704-3] reports that it might be out of date.                                                                                                                            I have done a manual update of Avast but im still getting this msg every time i boot up.
The program seems to be working fine.
Would any body know why this is??
I have done full scan and the VRBD  right up to date.
The machine is
dell 3100
windows xp sp2,
2.66 celeron,
248mb ram
80g hard drive.

Many thanks.
James

   Hi James :

     This has been covered many times in this forum; therefore, I recommend you use the "search"
     at the top of this page and use the search "term" "Windows Security Center" for the BEST
     advise . I always recommend ignoring that suspect "warning" .
