No GUI for Fedora Core 5

I have Fedora Core 5 on my system. I installed rpm file of Avast for Linux. It installed fine without any dependency error. However i am not able to locate a GUI for the application. I am to use application in terminal. Also every time i run Antivirus i have to enter Registration Key.

create ~/.avast/avastrc file
and insert these 2 lines into it:
[licence]
key=YOUR_KEY

Thanks i got it. The link was present in /usr/bin already. Working fine in GUI mode.
