Thanks for the welcome
Everything was working a treat (which is where I need to say how great Avast! is by the way
and then the other day I tried scanning an image (Epson Scanner) and tried to send it via. email which it said it had a virus in it. Since I just scanned it I doubted this and skipped it to try and send, however it refused to send the email.
Now whenever I try to read or send an email the pop up error occurs and I need to close off the box three or so times until it allows me to send or receive. Doesn't matter if the email has attachments or not. If it has attachments it says it cannot scan attachment.
Mail Scanner is on and everything updates so I assume it isn't blocked anywhere.
Hope that may be more help
