Yeah there doesnt seem to be a switch in the guide for it to kill the process after silent install. I've tested this: start /wait %systemdrive%\Install\Applications\AVGFree\avg_free_stb_all_2011_1191_cnet.exe /UILevel=Silent /InstallToolbar=0 /ChangeBrowserSearchProvider=0 /InstallSidebar=0 /ParticipateProductImprovement=0 /DontRestart /DisableScan Works great but then AVG opens and stays open until user interaction. Wth. Anyone find a solution yet? I was thinking of putting a killprocess command in my batch file, anyone know if .cmd files support that? And what would the avg pocess be called? Thanks for the help. EDIT: I've tried the above command with this right after: taskkill /IM avgui.exe /T /F It works and the batch files continues!
