Hi,
Not really into computers, I installed that antivirus after a recommendation.
I used McAfee before.
I can send emails and some with attachments but others will not go, if I remove the attachment the email will go.
I have tried sending them as original files and as PDF, the file is only 897kb which I normally sent out before and larger.
I assume it is something to do with the program setting as it has only started since installing Avast professional.
Dont know if that helps at all.
Graham
