Can't get command line scanning to work!! ashCmd not recognized, HELP!!!

I can’t seem to get the command line scanning to work at all. According to the help files how do you write out a correct command to execute a scan of c: drive ?

ashCmd is not a recognized command and I want to put a command line in my services files to invoke if a service fails to start the second time. Anyone a little help on the basics of how to construct a proper command line. Why aren’t the help files more helpful?? It’s too confusing

Nevermind. I found out it’s only available in the professional version. Sigh…

Do you have ashcmd.exe file? Are you using the Professional version of avast?
It is working here…
