Bypassing Notice to delete or save email message

[ve3fal]

Hello gang, new to the list, did a search but so many topics came up not sure where to look.
My question is that each time Avast finds a whitespace sequence or other email I get the splash screen that says suspicious message and to delete,block or continue..
My question is how do I get this to automatically block those messages for me without getting the warning and delaying my email.

Thanks
Fred
