Outlook XP

I have developed a small application for Microsoft Outlook - XP. I tried to drop some mails into the outbox. When each mail is dropped I recieve a warning saying "Virus Attack-Want to continue ?". If I have about 3000 mails then I have to say "NO" about 3000 times. This is a lumbersome one. Can any one suggest a way for clearing this problem ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Visual basic, Windows XP
