Re: [Trisquel-users] Need help with ClamTK GUI update.

[onpon4]

Actually, virus definitions are updated by running "freshclam". I don't know  
how you can do that manually in ClamTk if at all, but it's set up to do so  
automatically in some fashion; this is probably how you got your virus  
definitions updated, and it's probably sufficient. If you want to update them  
manually for some reason, though, you can do so by opening a terminal and  
typing "sudo freshclam". :)
