Ahh cheers Igor 
I had done it the way described above by DavidR, so it looked like this under the MailScanner section
IgnoreProcess=avast.setup
IgnoreProcess=MailWasher.exe
Will try it the way U have said Igor, many thanks
BaNzI ;D
EDIT: The line now looks like this IgnoreProcess=avast.setup,MailWasher.exe
But Avast is still checking & showing the details stripe when Mailwasher checks 
Does it need a reboot to take affect or can same be achived by stopping the providers & restarting them?
