Jeff.KeyesThe system tray is merely a component of AVG that runs / not running.
In the installation options page you can set the visibility of it as an option. Assuming you don't want to install just to show the icon.....you could also add the program "C:\Program Files\AVG\AVG8\avgtray.exe" to start up automatically.
If folks request this, we could add a little something to turn this on/off....but thus far, I've not heard lots of requests for it nor super good business case for it. (I love saying that...seems like I'll either get a lot of responses to tell me why this is the next coolest feature...or dead silence...which validates my point).
Jeff.KeyesIn the installation options, you can set whether to show the system tray or not. Once installed, we don't have an option to hide / show outside of reinstalling or running a script to re-enable.
leeevansThe tray icon can easily be enabled or disabled post-installation as it is simply a registry key.
Just create a script which adds or edits the following reg key
type = Reg_SZ
value = "c:\program files\avg\avg8\avgtray.exe
