How can you also include the anti-virus right click option? I have the silent install working a treat by extracting the files and running that command to install: CFPCONFG.EXE -i -s At last a proper silent install without all that AutioIt stuff! BUT I don't have any right click option to scan files and folders. I am looking in the registry to see if I can make a reg tweak for it. EDIT: No need for a reg tweak just register the cavshell.dll thats in the COMODO folder and its there, easy.
