Webuser Forums: Email /deleted folder

Hi all ,
I hawe peculiar happening sending Emails using My ISP address I say this as I am receiving mail from other address Like AOL/ Yahoo but not getting them delivered.
For instance if I try to send a email to some one in my ISP address folder including my self first it goes to the outbox folder then to my Deleted Folder, missing the Sent folder. there are no error messages at all.
if I try to send a email from my Aol account all seems to be in order showing in the sent folder but they are not being received.. As far as I know they are not being blocked I am using Ashampoo anti spy ware although not long installed (1 Month) I did not have any problem until this last week any suggestions appreciated.
Cheers

Ps I am still gettig the Quarantine list as normal from my ISP as usual but nothing else that sometimes has some legitmate mail that I can then retrieve.
Cheers
