Killbox.exe trojan

A couple of days ago my AVG detected & removed (Trojan horse BackDoor Hupigon3.XKF) from my computer.
I had Killbox installed, but fortunately have not had to use it to remove anything stubborn.  Have seen some other forums on Google that have had the same thing...was just wondering if I should re-install Killbox, or will I just be inviting the same problem again.  Computer is fine.  All scans are good.
Thanks.

Killbox does not update automatically.

It is a program that is better to download for use then delete it.

If needed later, always download a fresh copy.

Thanks for the info.

Merry Christmas.
