A FalsePositive question

I’m a programmer. I’m coding integrated commerical software.
I must use a few different programming language while developing.

When I compile a helper program with VTask automation, all antivirus softwares (including Avast) marks it a Virus!
I tried everything but nothing changed. Even I compile an ‘empty’ project with VTask, again it marked as a virus…

I also pack my program as a setup and it contains another temp setup recursive. Avast also marks this a virus.
Why all programs compiled with VTask is marking as virus? What can I do about this?
(I don’t have a choice except VTask because sometimes I need to use some interactive screen/mouse operations which is so hard to do with a classic program – eg: for Web Site interactive modules).

You need to make exclusions on avast! settings (exclude the VTask folder where the new compiled programs are being generated).
Won’t is solve it?
