False Positive?

This morning Avast warned me that my DCService.exe might be infected by Win32:Evo-gen. I uploaded and scanned it on Virustotal and they said the detection ratio was 0/51. Is this a false positive?

Here is Virustotal link:

Win32:Evo-gen [susp] = suspicious / a on access detection only so will not show on VT or when scanning

What am I supposed to do about this? When I build my C# app Avast reports win32:evo-gen in the .exe and deletes it.
I set it to exclude my project directory and built the .exe, but now Avast is blocking my creation of an installer which includes the .exe, so I cannot get a serious bug-fix release out. If I set Avast to exclude the installer creation files, I could create the installer, but I cannot put this online for people to use if Avast is throwing up alerts about it.

This sucks. I need to get this software release out.

What am I supposed to do about this?
report it using one of the options given above.....

Thats just strange. By commenting out a couple of lines of code, I can build my C# app and Avast is ok with it.
Unfortunately I really wanted those lines in there - just a minimum height check on a Windows control on my form.
Anyways, have posted a copy of the file with a false positive report.
