[RESOLVED] Sending a file

I wrote a program consisting of several forms and no special controls.

I compiled it and ran two anti-virus programs on it. It came out clean, as it should.

I compressed the exe and ran the same two anti-virus programs against it. It still came out clean.

I attached the zip file to an email and sent it to a friend. It bounced with the error msg
554: 5.7.1 [VI-2] Message blocked due to virus content of the message..

I tested it again by sending it to my second yahoo account. No problem. I then tried to send it to me backup email account on gmail. Same error message as when I tried to send it to friend.

I know there is no virus. I don't believe that I know how to write a virus. How do I send this compressed file?

Thanks
