How do you go about requesting updates of Instant Messengers to IM Shield? I have a Program I use called inSpeak, and I’d like it added to the list of instant messenger programs that Avast IM Shield Monitors for Viruses…
Welcome to the forums, dodgemurphy 
I so not think you can add IM programs yourself.
Maybe someone else will comment on this, maybe an avast employee will see this, and maybe they will consider inSpeak.
Anyway, don’t be worried, the File Shield is still protecting you against malware coming from inSpeak.
