Ok. I have been at this most of the day looking at the fedora documentation web site and other sites. I downloaded the free AVG anti-virus RPM package for Fedora. Then I double-clicked to install. Everything seems fine. But then where was that software installed? There is not START - All programs list as in Windows XP. I went into System - Administration - services and found the avgd deamon that runs in the background. But where is the user interface to the software? I went to System - Administration - Add/remove program but the AVG anti-virus program is not there. I went in the console and tried to remove the software with the RPM command (rpm -e packagename), but it said that there is no such package. Then I used the RPM command again (rpm -ivh packagename) to install the package, but it tells me that the package is already installed. Wow. This is all messed up. By the way, this is brand new install of Fedora from this morning. So it cannot possibly have messed itself up already.
How does one access a software installed from a download anyway? It is so easy in Windows XP but seemingly a nightmare with Fedora.
Any help would be appreciated.
