AVG antivirus update in Kubuntu

[WJ Seidl]

Thanks to all who responded to my problem.  I managed
to get the update by opening a terminal window and using the sudo 
avgupdate -o command
as suggested.  It still doesn't work in the GUI, but once I know (a lot) 
more about Linux, I will
work on that little issue.
Coming from a Windows environment, one is constantly reminded of the 
part of Murphy's Law
that states "Make something idiot proof, and the world will build a 
better idiot".  With virii today,
one can't be too careful; and for someone who (still) knows little about 
Linux, I wouldn't be able to tell if
something were amiss or not.  Lack of knowledge is a terrible thing, 
like trying to breathe vacuum.
There is certainly a steep learning curve to Linux, isn't there!
Thanks again to all who responded.
